I would say just the opposite. As you know, you have to be careful
(because parent/child is sharing memory) when you convert from fork to
vfork, so as a maintainer I wouldn't like to only do it for a very small
subset of machines (that he probably cannot easily test himself).

Either the conversion is correct, and should be done for everyone so it
keeps working or it shouldn't be done.
