# allow to silence error reporting for certain 'expected exceptions'

# gevent prints a error report including a traceback for each failed
# greenlet. this is at times useful, but you're currently forced to
# either handle exceptions in those greenlets or live with the traceback
# on stderr.

# patch_gevent introduces a class variable 'expected_exceptions' to
# gevent's greenlet class. This is a tuple of exceptions for which no
# error report should be printed to stderr.
