There was an old issue (fixed I thought) that caused the vm-natd process to runaway and consume a ton of CPU.
I see it about 2 times each day and have to restart the vmnat daemon in order to get it back down, so am not THAT sure it is fixed. 
Easy to reproduce here if one opens firefox with like 50 tabs on Windows XP and have another Windows 7 VM open at the same time (both using NAT) then it always happens. The issue didn't happen before Fusion 4.1 and only saw it very very rarely on Fusion 3.

edit: forgot to mention that's firefox with noscript extension and echofon extension. (might be relevant - or not)
