So first of all, I just want to echo the general sentiment here and say that all of this is beyond awesome. Cosmopolitan libc seems to have the potential to literally re-define what constitutes portable code.

With that out of the way, am I understanding correctly that the way this works on Linux/Unix is that the modifies itself (by overwriting the EXE file header with an ELF header)? This seems to have the consequence of making that specific file no longer portable. If I'm understanding things correctly, it also looks like the QEMU hack for non-x86_64 architectures will only work once per file, since after the first time running the file it will no longer run as a shell script on Unix so the QEMU invocation will be unreachable.

Have you considered adding workarounds for this?

On unix its a Thompson shell script that pipes an ELF binary to 'exec', I believe
