More info Re: [ZODB-Dev] ZEO select.error: (9, "Bad file desriptor")

Michel:

I didn't understand all of what you said so I put=20
try:
  ...
except:=20
  traceback.print_exc()

code into the handle_read() and handle_write() methods found in smac.py.

Below is the output from re-running my test.  The handle_read() exception=
 and=20
the close() function seems to be executed in parallel because the printed=
=20
output was mixed together during printing. =20

Thanks,
John
