[PATCH] bogotune-0.15.12

[David Relson]

Greetings,

This morning I discovered that the new version of bogotune has a memory
leak.  For each message scored, a 24 byte rstats_t struct is allocated
and not released.  If you're tuning 10,000 ham and 10,000 spam, the leak
costs 480,000 bytes (plus malloc overhead) for each scoring iteration
(of which there are 400 to 500 in a bogotune run).  The problem is fixed
by the following patch below.

David
