Alan M. Carroll commented on TS-1031:
-------------------------------------
This is something of a hack.
Longer term what would be better is to separate IO closure with re-allocation.
If we used something like Ptr (from lib/ts/Ptr.h) to reference count and not
put the VC back on the free list until the last reference clears, then this
would be far less of a problem. It is plausible that everything crash has
happened after a VC was free'd rather than just closed.
The one issue would be cross thread freeing, although that should not be a
problem unless there is a consistent drift of VCs to a single thread, although
it might be that VCs are really freed when the thread local free list grows too
large in which case this is just not maximally efficient.
