[ubuntu-mono] [Bug 28467] after one hour or so, cpu goes up to 100% and slows the whole system

Description:
when attending to classes, I use to leave my laptop on on the desk. When
I come back after one or two hours, it always requires one minute or
more to wake up completely just from the screensaver (no sleep or
suspend function).

after that, it is however running slower than ever. CPU is near 100%,
all apps require some thirty seconds to get started (i'm talking about
the gnome terminal, not firefox or OOo). The only solution to this is to
restart Ubuntu from zero :(

I tried to understand if there's an application that eats up CPU, but
what's more strange is that while it's, say, 98%, doing ps aux there is
no application with more than 3-4% CPU, and if I try to sum the value
for every process, it is something like 20 or 30, so I don't know where
to start from.

I have an updated Ubuntu Breezy. My system is a ACER Aspire WLMi1652
with Intel Centrino (i686). I use kernel 2.6.12-686
