--- Comment #48 from Saagar Jha <saagar at saagarjha dot com> ---
Hey, just stopping by a little late=E2=80=93since you've already merged a p=
atch for
this=E2=80=93with information that might be potentially helpful. I looked i=
nto this
several years back but never finished a patch for it, but my impression for=
 the
sporadic failures was that GDB multiplexes Mach messages through a port set=
 and
they would race to arrive. If they came in the right order then things would
work, and if not then it would hang. It's definitely possible that there's =
more
to the story or that I completely misdiagnosed the problem, but my impressi=
on
(from way back, mind you) was that the second wait was actually useful and =
the
hang was from this rather than the extra call. Just my 2 cents :)
