Description
hrev24417, VMware
While running a relatively harmless Perl test the page writer suddenly and unmotivatedly started to hog the CPU. As the attachment shows the count of the modified queue has become -1, which causes the semaphore acquisition to be skipped (sModifiedTemporaryPages is unsigned).

Probably fixed in hrev24430. That race condition would be a good explanation at least.
