+Subject: [PATCH] Disable signalfd by default
+
+signalfd may behave differently to sigaction/signal, so to avoid
+breaking libevent users (like [1], [2]) disable it by default.
+
+  [1]: https://github.com/tmux/tmux/pull/3621
+  [2]: https://github.com/tmux/tmux/pull/3626
+
+Also signalfd is not that perfect:
+- you need to SIG_BLOCK the signal before
+  - blocked signals are not reset on exec
+  - blocked signals are allowed to coalesce - so in case of multiple
+    signals sent you may get the signal only once (ok for most of the
+    signals, but may be a problem for SIGCHLD, though you may call
+    waitpid() in a loop or use pidfd)
+- and also one implementation problem -
+  sigprocmask is unspecified in a multithreaded process
+
