billiard is a fork of the Python 2.7 multiprocessing package. The multiprocessing package itself is a renamed and updated version of R Oudkerk's pyprocessing package. This standalone variant is intended to be compatible with Python 2.4 and 2.5, and will draw it's fixes/improvements from python-trunk.

  • This package would not be possible if not for the contributions of not only the current maintainers but all of the contributors to the original pyprocessing package listed here
  • Also it is a fork of the multiprocessin backport package by Christian Heims.
  • It includes the no-execv patch contributed by sbt.
  • And the Pool improvements previously located in Celery.
