 Features:
 
+* sd-event: compat wd reuse in inotify code: keep a set of removed watch
+  descriptors, and clear this set piecemeal when we see the IN_IGNORED event
+  for it, or when read() returns EAGAIN or on IN_Q_OVERFLOW. Then, whenever we
+  see an inotify wd event check against this set, and if it is contained ignore
+  the event. (to be fully correct this would have to count the occurances, in
+  case the same wd is reused multiple times before we start processing
+  IN_IGNORED again)
+
 * sd-stub: set efi var indicating stub features, i.e. whether they pick up
   creds, sysexts and so on. similar to existing variable of sd-boot
