Windows Handle Count

Hey all,

So, the problem tends to come up while I'm browsing the web with about 20
tabs open in IE (I have my reasons) and suddenly the next tab I try to open
won't come up. If I go to right click somewhere, the context menu won't
come up. If I close a tab, I can get the task manager to open. On the
Performance tab I'll find around 24,000 handles open. If I close a few
windows this goes down, and I can again do some stuff again but only until I
hit this magical ~24k limit. Has anyone else been seeing this? I've seen
this in XP previously, but it seems to happen a lot more often in Vista (I
suspect because I'm closer to the limit at boot). For the record this is
RC1 x86. Is there a hard handle count limit of some kind? I understand
that the more handles you have floating around the slower the system will
become, but this seems like a consistant restriction on how much can be
running.
