It looks OK but the Travis failure is messy, I can't tell whether this PR is causing it.

[jreidinger]

@mvidner me neither and it is strange that only push one and not pr one failed. Restarting job to see if it is just temporary issue.

@mvidner with additional debug output it now prints segfault. Sadly I cannot reproduce it locally, as rake osc:build skips this test ( so also BS is not affected ). Not sure what case it as I do not have core dump, but this change does not look like reason for segfault ( which is probably race condition ).

It skips because tmux is not installed. That can be solved with rake osc:build["-x tmux"]... and then it passes for me. :woman_shrugging:

[mvidner]

I tried various ways to reproduce the test failure locally but it always succeeded. So I restarted the Travis job and now it is green.
