There are a dozen different Unix-like systems with slightly different
behavior. I care about all of them. It should be possible to at least
test some BSD versions. But there are also SYSV derivatives that
matter, such as HPUX.
It's difficult to test everything, that is why I prefer to make minimal
changes that actually solve a problem. If we don't know why that
setsid() was there, then removing it probably breaks something.

MONK: ... and the Lord spake, saying, "First shalt thou take out the Holy Pin,
then shalt thou count to three, no more, no less. Three shalt be the
number thou shalt count, and the number of the counting shalt be three.
Four shalt thou not count, neither count thou two, excepting that thou
then proceed to three. Five is right out. Once the number three, being
the third number, be reached, then lobbest thou thy Holy Hand Grenade of
Antioch towards thou foe, who being naughty in my sight, shall snuff it.
