I have a Windows 2008 Slave machine.

As a workaround of issue #3973 I've created a periodically scheduled dummy build
on the slave as "ping". Unfortunately it seems after a some time this dummy
build makes the slave unusable.

The dummy build contains no build steps and no publishers. and it is tied to the
slave.

I've tested with a not so dummy build when I've just executed a Windows batch
command: time /t
At this case the slave went unusable with OOME as it couldn't create more
NativeThreads.
