Someone would probably have to do a decent amount of work to figure out how to 
get fork emulation working natively under Arm64 Windows, and other critical core 
emulation functions, on Arm64 Windows machines, probably as part of a paid or 
lengthy academic project, to donate to the volunteer Cygwin project.

Any CS/EE PhD candidates out there looking for a project, or embedded engineers 
needing to support POSIX toolchains and environments under native Arm64 Windows?
