Ticket #4109 (closed defect: invalid)
Default OS processes consuming lots of CPU during and after running VirtualBox - hard reset required.

I recently noticed some strange behavior with my macbook pro where processes seem to consume lots of CPU for no apparent reason. The only common denominator seems to be VirtualBox.
- Boot into OSX launch VirtualBox and run a Win2003 Virtual machine - everything seems fine.
- Download some OS updates for the VM (win2003) and lauch safari or firefox on the mac - everything seems fine
- close/reopen safari a few times and launch system preferences - notice CPU % value of 125% in top. Close VM down and notice other processes consuming lots of CPU. Even top starts to report it's own process at about 30-40%. Idle CPU % values basically stay around 0-5% and the OS becomes unusable.
After rebooting the OS everything seems fine. At the moment I can't recreate the issue unless I run Virtualbox at some point.
Tested with VirtualBox version 2.2.2, 2.2.0, 2.1.4 (haven't tried previous versions) Tried with Mac OSX 2.5.6 and the latest update 2.5.7
Mac Details - OSX Version 10.5.7 Mem 8GB 667 Mhz DDR2 SDRAM Processor 2.4 Ghz Intel Core 2 Duo
Looks like some sort of race condition occurs on the default mac processes after using VBox.
Any help would be appreciated.
