Test the default SIGUSR1 signal

  $ hg signal USR1 2>&1 | tail -1
  * written to $TESTTMP/dump-*.log (glob)
  $ ls $TESTTMP/dump-*.log
  $TESTTMP/dump-*-*.log (glob)
  $ grep Thread $TESTTMP/dump-*.log | head -n 1
  Thread *: (glob)
  $ rm $TESTTMP/dump-*.log

Test the signal config option

  $ echo 'signal=USR2' >> $HGRCPATH
  $ echo 'memsignal=USR1' >> $HGRCPATH
  $ hg signal USR2  2>&1 | tail -1
  * written to $TESTTMP/dump-*.log (glob)

Test the interval config option

  $ newrepo

  $ hg dbsh -c 'import time; time.sleep(2)'
