-Subject: [PATCH 1/2] Fix behaviour of 'epoll-wake!' after 'run-fibers'.
-
-This avoids the "epoll instance is dead" error noticed in
-GNUnet-Scheme's test suite, as reported at
-<https://github.com/wingo/fibers/issues/61>.
-A test is added in the next commit.
-
-This patch has been applied upstream, but there hasn't been
-a new release yet at time of writing.
-
-* fibers/epoll.scm (epoll-wake!)[dead]: Instead of throwing an error,
-just return #t.
