racing commit push a new head behind another named branch
---------------------------------------------------------

non-continuous branch are valid case, we tests for them.

#  b (branch default)

#  o (branch foo)
#  |
#  | a (raced, branch default)
#  |/
#  * (branch foo)
#  |
#  * (branch default)

Creating changesets

(update default head through another named branch one)

  $ hg -R client-other/ up 'desc("C-Z")'
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo aaa >> client-other/a
  $ hg -R client-other/ commit -m "C-O"
  $ echo aaa >> client-other/a
  $ hg -R client-other/ branch --force default
  marked working directory as branch default
  $ hg -R client-other/ commit -m "C-P"
  created new head

(update default head)

  $ hg -R client-racy/ up 'desc("C-Z")'
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo bbb >> client-other/a
  $ hg -R client-racy/ branch --force default
  marked working directory as branch default
  $ hg -R client-racy/ commit -m "C-Q"
  created new head

Pushing

  $ hg -R client-racy push -r 'tip' > ./push-log 2>&1 &

  $ waiton $TESTTMP/readyfile

  $ hg -R client-other push -fr 'tip' --new-branch
