I've read that mutt will do that if hcache points to a dir and not 
a file. For things like multiple mutts (I use this with multiple 
mutt -F muttrc-thisconfig mutt -F .muttrc-thatconfig) define a 
hcache per mutt so in .muttrc-thisconfig it'll point to
~/tmp/hcache-thisconfig) it is quite blazingly fast.
