[-- Attachment #1 --] Hello, Early this year I've reported to the Python developers a problem in Python that has been triggered by peculiarities of processing of signals in FreeBSD together with a third party patch committed to the Python 2.4 ( http://bugs.python.org/issue960406 ). The detailed description of the problem with example script and patch you can find here: http://bugs.python.org/issue1975 Anyway the issue has stuck since then so I'm submitting the patch here so it can be included in the FreeBSD Python ports. P.S. Just in case I've attached the patch to this message. The patch is compatible with all versions of Python from 2.4 through 3.0. -- Kind regards, Andriy Pylypenko Development Lead Sippy Software, Inc.
