You can browse the source for the Memcache++ Client here:
http://memcachepp.svn.sourceforge.net/viewvc/memcachepp/trunk/memcache%2B%2B/
(or http://tinyurl.com/3yr7ju) -- It may just be the machine I'm
running on has a defect of some sort (memory corruption?) or some
hardware problem(s). That said, that's the last thing I would be able
to look into at the moment.

Hmmm... That's odd. I'm pasting the cpuinfo for the system here --
maybe something there will help. And btw, there are 4 processors in
the system like this. There's also 4 GB of RAM available.

processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6
model           : 15
model name      : Intel(R) Core(TM)2 Quad CPU           @ 2.40GHz

cpu MHz         : 2400.123
cache size      : 4096 KB

I hope this helps.
