I'm sorry, I don't see where that message says that modifying
mmap/munmap would break fork.  The reference to fork was as an example
of how it might be done.  I appreciate the fact that Zack has looked at
the Cygwin source, I still say that the effort would be best spent in
the runtime, not a package workaround that may break in future runtime
changes.
