 Hi zwol. Are you sure about this? I just tried making this tweak...

 https://gitweb.torproject.org/user/atagar/stem.git/commitdiff/4f38835

 ... and Stem's integ tests pass. I'm not sure if this fixes the issue
 where tor seizes up, but tor seems to gracefully handle the closure of
 stdout/stderr.

 Would someone running into this issue mind giving this change a try?
