Vladislav Vaintroub	c216c9f0f0	Allow for faster creation of threads in corner cases where pool would be overloaded with long non-yielding queries. ... To allow it, change minimum of thread_pool_stall_limit to be 10 milliseconds. Also introduce a new parameter to oversubscribe a group . Number of threads running in parallel would be higher than it normally should, leading to thrashing, but it may improving preemptiveness, which is useful for the described corner case.	2011-12-31 05:24:11 +01:00
