[Bug-gnubg] Memory hog!

[Ian Shaw]

GnuBg is hogging 400 MB of RAM!
I'm doing a 1620 2-ply rollout of an early game position. I'm running the 
030204 build on a Windows 2000 P4 2GhZ PC with 512 MB RAM.
The cache is set to 65535. At the reported 50 bytes per entry, this should only 
use up about 3.2MB. When idle, GnuBg seems to use about 16MB, so I wouldn't 
expect to see more than 20 MB used.
Could there be a memory leak somewhere?
