It turns out that we were both maligining QNAP here.

I installed strace (which I hadn't expected to be able to do, but 
there's an ipkg for it), and ran 2.1.17 through.

The log file stopped at:
16:55:35.549868 stat64("/share/MD0_DATA", {st_mode=S_IFDIR|0777, st_size=4096, ...}) = 0
16:55:35.550006 stat64("/proc/fs/nfsd", {st_mode=S_IFDIR|0755, st_size=0, ...}) = 0
16:55:35.550163 stat64("/.eaccelerator.tmp", {st_mode=S_IFDIR|0777, st_size=360, ...}) = 0
16:55:35.550300 stat64("/var/syslog_maildir", {st_mode=S_IFDIR|0777, st_size=40, ...}) = 0
16:55:35.550438 stat64("/mnt/thecus", 

It's checking the machine's mount points, and that last is where I'd had 
my old NAS mounted, to slurp the data off it. I'd then powered down the 
NAS, but hadn't unmounted it first, so I'd left a stale NFS handle, 
which caused the newer versions to hang (it's possible that they'd have 
eventually timed out and started up normally, but I'd never given them 
long enough).

umount -l /mnt/thecus, and everything runs fine.

Would it be worth generating a log message before checking the mount points?

Complete silence, pretty much as I'd expected!
