Statics make great memory caches.  :-)

Well, I've used it _ONCE_ in a growable stack... but only once.  ;-)  The 
worst part is that even though realloc is a standard function, it worked on 
gcc for OS/2, but failed in one circumstance on gcc for Sun... so I had to 
work around their bug.  Why?  Because it is (properly, IMO) underused, thus 
undertested.  Fine by me, though.  :-)
