Yes I waited more than 24 hrs but I would assume it would a few minutes
would do it as well. I am using gentoo and dovecot 2.2.19. I get numbers
for all columns except disk_input, disk_output, read_count, read_bytes,
write_count and write_bytes which is 0.

cat /proc/self/io
rchar: 2068
wchar: 0
syscr: 6
syscw: 0
read_bytes: 0
write_bytes: 0
cancelled_write_bytes: 0

Is this a kernel setting that causes this read_bytes and write_bytes to
be 0 as it happens on a test server as well.
