[Zope3-Users] bug on HP-UX 11.00

[Chris Leonello]

Stack size doesn't seem to be the issue.  The HP box is set
to 31116 Kb.  The recommendation on early releases of Mac
OS X was 4096 Kb.  Good idea though!

Does anyone have any ideas on why the unittest would fail?
Specifically, the testLargeBody method in test_httpserver.py?
it calls a method "loop":

def loop(self):
    self.thread_started.set()
    while self.run_loop:
        self.counter = self.counter + 1
        #print 'loop', self.counter
        poll(0.1)

which loops forever.  Why would this happen on HP-UX and 
not on other systems?  I'm not to familiar with socket
programming and the poll() call.  Is there some peculiarity
with the underlying poll() and select() calls on HP-UX
that I have to make adjustments for?

I really appreciate any tips or insight!
