I've been having the usual "thread program hanging" problem on -current.
It's my perception -- certainly not confirmed by anything analytic -- 
that the problem occurs more when galeon (the program where I usually 
see this) has been idle and is paged out.  Not sure if that's a helpful 
clue or not.  (My kernel and libraries are from about a week ago.  I 
may install today's build this afternoon.)
