Confirm.  This is *still* related to that uksort() call in IMAP_Sort:: - I
thought I had it figured out last night but today I logged in and it is
segfaulting again.  I quite honestly am out of ideas as to why this is
occurring.  I would hate to scrap uksort() for a hackish workaround 
solution if
the problem is something in our code.  But my only guess as to why the 
segfaults
are occurring is there has to be a bug in either uksort() or the fact that we
are calling uksort via a bunch of references and the fact that it is using a
reference itself is tickling some sort of obscure, memory allocation bug in
PHP.  But that is a wild guess.
