For some reason, the $SUMMARY test fails intermittently, especially on slower
machines. The test does not ever fail on my x86_64 dual core machine, but on my
single AMD machine it fails 1 out of 3 times I run it. I have bumped the
timeout between commands to 2 seconds but it still fails. I do not want to bump
the timeout any higher as it would slow down the test suite dramatically.
I added a test to TestKillCommand(testKillCommandTest) that this bug blocks.
See the test testKillCommand on how we added a wait to make the test pass.
Also, quit was causing problems too in the test sequence.
