I took a look at this.  It seems to be related to a recent change I
made which stopped cygwin from calling DuplicateHandle on every handle
after a fork, to reproduce the close-on-exec status.

The close_secret_event handle wasn't being created with the correct
inheritance type.  I (hopefully) changed this.

I did some rudimentary testing but I can't test it too heavily since
I'm setting up a new system.  My Windows 2000 system got a little
flaky over my vacation.  I think it didn't like being turned off for
so long...
