Hi!
  Well, Process Explorer don't show these leaking events at all, only
command-line
utility handle.exe from SysInternals shows them (don't know why).
Ok. I will try Cygwin 1.3.3 as soon as possible.

Ivan

then i think you should try to. 1.3.3 contains a lot of fixes/changes

do you mean it doesn't show names of all events or only those that are
leaking? HandleEx does show the names for named events, so we have 2
possibilities here -- either these are anonymous events (which may
help to track them down) or Process Explorer is missing needed
functionality in which case you should try to use original HandleEx.
