# There are three kinds of suppressions in this file.
# 1. Third party leaks we have no control over.
#
# 2. Intentional unit test errors, false positives
# in our own code, or leaks that are so trivial they are not worth fixing.
#
# 3. Suppressions for real WebKit bugs that are not yet fixed.
# These should all be in webkit's bug tracking system
# Periodically we should sweep this file and the bug tracker clean by
# running overnight and removing outdated bugs/suppressions.
