Subject: A 4999 entry hashtable is too small when there are a huge number (500k
X-Git-Tag: svn/VALGRIND_3_0_0~566

A 4999 entry hashtable is too small when there are a huge number (500k
ish) of blocks simultaneously live, and the client is doing intensive
malloc/frees.  Increase the table size 16-fold.
