I quit using mmap_disable around 7.1-STABLE and haven't had that bug since then. I'm running 8.0-R with Maildirs in a compressed ZFS dataset right now with no problems. That's pretty odd...I'm pretty sure it was in the implementation and had nothing to do with the ZFS version but I assume your datasets and pools are all updated to the latest version?
uname -v
FreeBSD 8.0-STABLE #2: Wed May 12 21:13:40 CEST 2010
zfs upgrade
This system is currently running ZFS filesystem version 3.
All filesystems are formatted with the current version.
zpool upgrade
This system is currently running ZFS pool version 14.
All pools are formatted using this version.
I can't really be more up to date than this...
Only thing is that Maildirs are all on different datasets, since every user has his own set.
mmap_disable made the problem completely go away.

I've seen this a FEW times. Like 3 in the last six months. seems to have gone away after updating to 1.2..though maybe I just haven't triggered it again.
I have one around every 5 minutes.

I guess it occurs when users are polling their mailbox, and maybe only with specific clients?
I have no clue.
P.C.
