Suggest changing dirhash defaults for FreeBSD 9.2.

[Robert_Burmeister]

Observation relevant to tuning vfs.ufs.dirhash_maxmem:

When swap is in use
dirhash_mem hovers between 10% and 20% of dirhash_maxmem
due to frequent scavenging.

This indicates active dirhash_mem effectively behaves differently during low
memory,
and that the dirhash_reclaimage setting is effectively irrelevant during low
memory.
