I periodically think about posix_spawn and the potential to fast-path simple cases to one of the spawn functions instead of a fork/exec. This should give a relatively good effort to performance improvement ratio. Also, the idea to use udis86 (or some other disassember library) to find_fast_cwd on x64, and adding code for arm64 hosts (which I've already prototyped but not tried to integrate into Cygwin).
