Comment:
I think i (patrially) figured this out...
Looks like there is a bug either somwhere in tahoe or foolscap that causes
foolscap.eventual._SimpleCallQueue._turn to be scheduled with a delay of
NaN.
From what i can see the methods in _SimpleCallQueue allways install it
with reactor.callLater(0, self._turn) - so it is somwhere else.
Anyway, this triggers a bug in twisted that makes the delayed call stick
in reactor._pendingTimedCalls forever and no later timed calls get
processed. Also in this state reactor.timeout() returns 0 and the reactor
starts iterating without delay causing 100% CPU load.
