* coroutines: Use one global bottom half for CoQueueKevin Wolf2011-08-021-13/+6
| | | | | | | | | | Now that AsyncContexts don't exist any more, we can use one global bottom half for restarting coroutines instead of allocating a new one every time (before removing AsyncContexts, the problem with having a global BH was that it had to belong to a single AsyncContexts and wouldn't be executed in a different one - which leads to deadlocks) Signed-off-by: Kevin Wolf <kwolf@redhat.com>
