An implementation is available at
You just need to stick
at the beginning of the program to use fork+exec instead of fork. The
test suite passes. (I would not say that making this work was that
That branch also supports the starting of processes via a server
process. That gives an alternative solution to the problem of mixing
fork() with threads, but has the advantage of being as fast as the
default fork start method. However, it does not work on systems where
fd passing is unsupported like OpenSolaris.
