I was more hoping it would at least turn the deadlock into a fail,
this way I could at least run the test suit.

Anyway, the actual issue is related Python 3: Arch Linux (and probably
some other distributions that "already" upgraded to Python 3 as
default) will launch Python 3 when the test script calls `python ...`.
And for some reason in Python 3.7, we will not inherit our FD from our
pipe to the subprocess, which causes this strange behavior when write
to the unrelated FD number in ConnectToRemote. When I explicitly call
Python 2.7 from the test, everything runs as expected.

The python docs don't see to mention this change (and it seems like a
bug to me), so I'm open for ideas how to fix this properly. In any
case this problem doesn't block this review.

(I hope this comment shows up in Phabricator, as it seems
reviews.llvm.org is currently having some internal errors).
