Well, it is obviously not like this, httpd father process is forking,
the service stops (so it is logged in eventlog), but cygrunsrv 'task'
is still running.
I think Apache is forking off some child processes, but it is not
exiting. So cygrunsrv process is active and Apache is running.
Normally the original (father process) of Apache is killed to
stop it.
But in eventlog it is this message control panel shows service is not
running.
The behaviour if i try to stop Apache (which is running, but it is
not running) with cygrunsrv is:
$ cygrunsrv -S 'Cygwin Apache'
$ ps -e

Hmm, here cygrunsrv isn't shown as active task,
or in process-list in the taskmanager.
But in the applicationlist of taskmanager it is shown two times now.
Does it follow the childs?
What is w*ndows showing here?

I am able to kill it now if i shut down the second cygrunsrv process
in the first register of Task-Manager.
Oops, shut down the wrong, (cron-service), at first...
There is no number, cygrunsrv is not listed in task list,
i am not able to kill any of the httpd tasks, but now it is
off.
