Not really a great argument for prioritizing POSIX, sadly.

That's not different from Linux and X11.

With X11, using fork is fine -- you just have to make sure that you only use that connection in one of the children. The bug report I linked to is Apple explaining that you cannot use their *linear algebra library* (which implements the standard, cross-platform BLAS interfaces) on both sides of a fork, and that the only solution is to use a different linear algebra library.
[NB I don't use OS X or really care about it either way, except that these things are annoying to work around.]

In particular, important parts of OS X are fork-safe. Moreover, OS X has support for code confinement and process isolation.
