Summary: pd eats all processor resources after suspend

Initial Comment:
yes, its like that. pd eats all aviable processor resources after suspend until i close it. i have compiled version 0.42.5 without any errors on my ubuntu karmic (x64), using  AMD Turion MK-36

Message:
With Pd 0.41.4 extended on OSX 10.5 the same behaviour happens. More
specific I have noticed this: a switched-on metro object will send all it's
suspended messages at wake up after sleep. This makes Pd using 99% cpu
during some time, depending on the length of sleep period.

Message:

An example patch is always very helpful, especially if it triggers the
problem every time that it is run.  Ideally the example patch would have
only enough objects to cause the problem, but nothing else.

ok, i logged in.
yes, but it is curious, why pd have to compute everything what had to be
done during sleep? it sounds useless.
i tried suspend my computer (for 5sec) with opened pd, but without opened
patch, it happens again - eats all aviable cpu (until i kill the proces),
but no patch opened.

Message:
i can't reproduce this : 
pd 42.5 ubuntu karmic i386

however, after suspend, pd have to compute everything that as not been
computed during suspend. so it can eat all cpu for some time, until it sync
again with real time. this is only if a patch that use cpu is open during
suspend.
