I should probably mention that my boss at covalent once wrote fork() for
Windows. He gave it to Will Rowe and I to look at with an eye towards
fixing a few bugs and getting it into APR. However, as Will started to
really dig into the code, he noticed that it wouldn't work for _MOST_
Windows apps. The problem was DLLs. Basically, the DLL had to be written
to work with fork(). Obviously, no native DLLs are. This is why cygwin
can work, they don't have to deal with native DLLs.
BTW, I once investigated every way to Sunday to get fork() working on
Windows. It was a major goal of mine, but it turns out to be impossible.
