Thanks to Laurie Brown <laurieb@mac.com> we have a version of 
secmem.c that makes mlock work on OS X.  I've pasted a diff below. 
Anyway, I'm brining this here to see what needs to be done to get 
this fix implemented (I realize that patching config.h is not the 
right thing to do, but it's the thing that she got working :-)).
