Test hgsql tries to sync before entering the critical section

  $ . "$TESTDIR/hgsql/library.sh"
  $ disable treemanifest
  $ setconfig hgsql.verbose=1

  $ newrepo state1

  $ cd $TESTTMP
  $ initserver repo1 master
  $ initserver repo2 master
  $ initserver repo3 master
  $ initserver repo4 master

Repo1: 2 commits. Sync them to the database.

  $ cd $TESTTMP/repo1
  $ hg pull -r tip $TESTTMP/state1
  [hgsql] got lock after * seconds (read 1 rows) (glob)
  pulling from $TESTTMP/state1
  adding changesets
  adding manifests
  adding file changes
  added 2 changesets with 2 changes to 2 files
  adding remote bookmark A
  adding remote bookmark B
  [hgsql] held lock for * seconds (read 5 rows; write 10 rows) (glob)

Repo2: Emulate client push. Hold the lock for long.

  $ cd $TESTTMP/repo2
  $ hg  --config hooks.pretxnclose.dely='sleep 6' pull -r tip $TESTTMP/state2 &>out &
  $ disown

Repo 3: Emulate client push to sql, after repo2.

  $ sleep 2
  $ cd $TESTTMP/repo3
  $ hg  --config hooks.pretxnclose.dely='sleep 6' pull -r tip $TESTTMP/state3 &>out &
  $ disown

Emulate writing to another repo when the lock was held elsewhere.
Explaination:
- The first "getting 2 commits from database" is because repo4 is empty, and the database has A,B synced from repo1.
- The second "getting 1 commits from database" is because repo2 push completes.
- The third "getting 1 commits from database" is because repo3 push completes.

  $ cd $TESTTMP/repo4
  $ setconfig hgsql.syncinterval=0.1 hgsql.debugminsqllockwaittime=13
  $ hg pull -r tip $TESTTMP/state4

Make sure repo2 and repo3 log looks sane.
