I did a lot of fixes related to this and since I haven't heard of it
happening for a while now with latest 2.0.x versions, I think I managed
to fix it..

Unfortunately RHEL6 was frozen early during v2.0 development before all
the bugs were fixed. RHEL6.1's Dovecot is hopefully a pretty good one.
Until then, I'm not sure what you can do to avoid the above problem,
other than upgrade to a newer v2.0. You could try if this helps:

service imap {
  process_min_avail = 12
}
