Jun Wu 7a66e96504 copytrace: avoid phase operations with narrow-heads
Summary:
With narrow-heads before the new dag structure, reading phases is expensive.
Avoid it.

This is part of a stack of optimization that makes a 20s rebase to 5s (0.6s per
commit to 0.07s per commit).

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.
