[Zope] RE: Zope 2.4.3 crashing continually - asyncore replacement?

[Jin Choi]

Problem solved. Thanks for your help. Looking through old mailing list 
archives, I see that this is a fairly well-known problem (but still not 
fixed in either asyncore.py or in Python!) Anyway, I took some code from 
ZEO's asyncwrap.py and modified asyncore. This really should get fixed 
once and for all....
