Another follow-up on my first posting:

Those commands take almost one(!) second to complete. I've used strace to capture what happens and made the results available at http://www.incertum.net/~cite/imap.log.
Comaring this to a 1.0.15, the main difference seems to be that the "dovecot-uidlist" file is rewritten every time I issue a "STATUS" command. Here's what 1.0.15 does:
read(0, "a0071 STATUS \"postfix-users\" (UID"..., 4072) = 66 setsockopt(1, SOL_TCP, TCP_CORK, [1], 4) = 0 stat("/export/vmailboxes/c/cite/Maildir/.postfix-users", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 stat("/export/vmailboxes/c/cite/Maildir/.postfix-users/cur", {st_mode=S_IFDIR|0700, st_size=1650688, ...}) = 0 stat("/export/vmailboxes/c/cite/Maildir/.postfix-users/new", {st_mode=S_IFDIR|0700, st_size=36864, ...}) = 0 stat("/export/vmailboxes/c/cite/Maildir/.postfix-users/tmp", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 stat("/export/vmailboxes/c/cite/Maildir/.postfix-users", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 stat("/export/vmailboxes/c/cite/Maildir/.postfix-users/dovecot-shared", 0x7fff35082530) = -1 ENOENT (No such file or directory) brk(0x8b0000) = 0x8b0000 gettimeofday({1249300019, 466489}, NULL) = 0 open("/export/vmailboxes/c/cite/Maildir/.postfix-users/dovecot.index", O_RDWR) = 7 alarm(120) = 0 fcntl(7, F_SETLKW, {type=F_RDLCK, whence=SEEK_SET, start=0, len=0}) = 0 alarm(0) = 120 fstat(7, {st_mode=S_IFREG|0600, st_size=289344, ...}) = 0 mmap(NULL, 289344, PROT_READ|PROT_WRITE, MAP_SHARED, 7, 0) = 0x7fde2d02c000 open("/export/vmailboxes/c/cite/Maildir/.postfix-users/dovecot.index.log", O_RDWR) = 8 fstat(8, {st_mode=S_IFREG|0600, st_size=296440, ...}) = 0 pread(8, "\1\0\30\0Y\315vJ\1\0\0\0\0\0\0\0\0\0\0\0Y\315vJ"..., 24, 0) = 24 fcntl(7, F_SETLK, {type=F_UNLCK, whence=SEEK_SET, start=0, len=0}) = 0 access("/export/vmailboxes/c/cite/Maildir/.postfix-users/cur", W_OK) = 0 stat("/export/vmailboxes/c/cite/Maildir/.postfix-users/new", {st_mode=S_IFDIR|0700, st_size=36864, ...}) = 0 stat("/export/vmailboxes/c/cite/Maildir/.postfix-users/cur", {st_mode=S_IFDIR|0700, st_size=1650688, ...}) = 0 fstat(7, {st_mode=S_IFREG|0600, st_size=289344, ...}) = 0 stat("/export/vmailboxes/c/cite/Maildir/.postfix-users/dovecot.index", {st_mode=S_IFREG|0600, st_size=289344, ...}) = 0 alarm(120) = 0 fcntl(7, F_SETLKW, {type=F_RDLCK, whence=SEEK_SET, start=0, len=0}) = 0 alarm(0) = 120 fstat(8, {st_mode=S_IFREG|0600, st_size=296440, ...}) = 0 mmap(NULL, 296440, PROT_READ, MAP_SHARED, 8, 0) = 0x7fde2cfe3000 madvise(0x7fde2cfe3000, 296440, MADV_SEQUENTIAL) = 0 fcntl(7, F_SETLK, {type=F_UNLCK, whence=SEEK_SET, start=0, len=0}) = 0 gettimeofday({1249300019, 471527}, NULL) = 0 write(1, "* STATUS \"postfix-users\" (RECENT "..., 111) = 111 setsockopt(1, SOL_TCP, TCP_CORK, [0], 4) = 0 gettimeofday({1249300019, 471961}, NULL) = 0 epoll_wait(4, <unfinished ...>
As you can see, dovecot-uidlist istn recreated.
Is this intended behaviour, some unfortunate side effect of mounting the partition with "relatime" or something completely different, perhaps something about my plugin (quota, sieve, fts)?
