squatter feature request

[Matt Bernstein]

Hi,

Since running squatter twice daily, I have a lovely performance boost for 
searches at the expense of almost doubling the space my mail store 
occupies. Great :)

I don't care squat (sorry) about the cyrus.squat files, and I'd like them
not to be backed up every night.

With my system (Linux/ext3) I can do:
  find /var/spool/cyrus/mail -type f -name cyrus.squat -exec chattr +d {} \;
..after every invocation of squatter, but I'd like to request that 
squatter does this itself.

The patch would be easy for my system, but I suspect it wouldn't be at all
portable--I don't think ioctl(3, EXT2_IOC_SETFLAGS,...) would work on a
Solaris system ;)

Cheers,

Matt
