list mechs bug in cyrus-sasl 2.1.22 and memory leak

[Quanah Gibson-Mount]

Me too.  This problem only occurs on the Mac (PPC or i386), and does not 
show up on linux at all.  I'm guessing this is due to the Mac having a 
slightly different source tree.  I've verified it goes back as far as 
2.1.18.

The multi-listed mechanisms was what pointed me in the direction of SASL, 
as that was what showed up in the OpenLDAP backtrace.
