Jean-Daniel Cryans updated HBASE-1008:

Patches for 0.19 and trunk with the number of threads as a constant and with more javadoc
comments. Would need a +1 from someone who tested it please.

> Watching recovery from a crash on streamy.com where there were 1048 logs and repay is
running at rate of about 20 seconds each.  Meantime these regions are not online.  This is
way too long to wait on recovery for a live site.  Marking critical.  Performance related
so priority and in 0.20.0.
