-Subject: [PATCH 1/2] Revert "loop: remove destroy list"
-
-This reverts commit c474846c42967c44db069a23b76a29da6f496f33.
-In addition, `s->loop` is also checked before dispatching a source.
-
-The destroy list is needed in the presence of threads. The
-issue is that a source may be destroyed between `epoll_wait()`
-returning and thread loop lock being acquired. If this
-source is active, then a use-after-free will be triggered
-when the thread loop acquires the lock and starts dispatching
-the sources.

-Add test which tries to destroy an active source precisely
-after the loop has returned from polling but has not yet
-acquired the thread loop lock.
