Gregory Nutt	0218f01f12	If there mutliple low-priority worker threads, only one needs to perform garbage collection	2014-10-11 07:09:21 -06:00
Gregory Nutt	234f73cb09	Add logic for priority inheritance with multiple worker threads. How should this work? Tentatively, the all get reprioritized together. It would be best to just reprioritize the single thread doing the high priority work, but we don't know which that will be in advance	2014-10-10 17:47:39 -06:00
