[lldb-dev] TestAttachDenied - timing out

[Oleksiy Vyalov via lldb-dev]

Test used to be flaky from time to time but in
http://lab.llvm.org:8011/builders/lldb-x86_64-ubuntu-14.04-cmake/builds/6802
it failed consistently for all configurations - that's pretty suspicious.
Test inferior writes some output to stdout and stderr - I don't have a lot
of context about http://reviews.llvm.org/D13124 but as I can see all
standard streams are set to subprocess.PIPE, as a guess
maybe inferior tries to write sth in stdout/stderr but nobody is reading
this data on python side.
