1) Fix leaks in error paths (bfind.c -- found by inspection).
2) Don't allocate hash table data out of the arena. PL_Hash grows and shrinks
the hash buckets as necessary. In arenas they will just grow.
3) Don't allocate temparary locks out of the global instance arena pool.
keys go into and out of the table. the old code allocated the keys from

table.
