[lldb-dev] TestEvents test case causes python runner to dump core

[Matthew Gardiner]

If I revert Greg Clayton's change r220113, then the core dump problem
vanishes.

I also found that running with r220113, but with the invocations of
SetAsync(True) removed, see below:

also fixes the core dump, but leaves us with a couple of failing cases.

Greg, could you fix this, so that your change does not have to be
reverted in order to get the linux python tests to run?

thanks
Matt
