Durham Goode 1186282722 workers: flush mutable data before forking workers 
Summary:
We encountered a bug where if a file descriptor was not flushed prior
to forking the process, then both processes would end up flushing the same data
to the file, resulting in duplicate data and a corrupt file.

The real fix is to stop using fork, but for now let's address the most visible
problem by flushing pack files before forking.

Mercurial
=========

Mercurial is a fast, easy to use, distributed revision control tool
for software developers.

Basic install::

 $ make            # see install targets
 $ make install    # do a system-wide install
 $ hg debuginstall # sanity-check setup
 $ hg              # see help

Running without installing::

 $ make local      # build for inplace usage
 $ ./hg --version  # should show the latest version

See https://mercurial-scm.org/ for detailed installation
instructions, platform-specific notes, and Mercurial user information.
