Slava Pestov	70dcecf61a	vm: don't flush instruction cache twice per code block on a major GC on PowerPC	2009-10-15 22:31:41 -05:00
Slava Pestov	45eb68fa38	vm: during tenuring stage of aging collection, if tenured space fills up, it would attempt a to_tenured collection. this will succeed if all roots were tenured. however, this is unsound, because there's now an untraced segment of tenured space. fix: if tenuring fails, go on to do a full collection instead	2009-10-15 05:51:11 -05:00
