I just now also realized that it's not even necessary to flush globals. Their re-import will flush them anyways.

Only $_FILES needs to be flushed or it will segfault, still curious why.

Also surprised that noone has so far complained about $_REQUEST not being supported in worker mode. It will only work if it's jit is disabled.

Alright, I think I finally figured out a cleaner way to reset globals.

Insterestingly, only $FILES will not be flushed on import, all other globals are flushed.
see: $_GET $_POST $_COOKIE $_SERVER $_ENV $_FILES $_REQUEST

I think it might make sense to document that $_REQUEST is only supported in worker mode if auto_globals_jit = Off (unrelated to this PR).

Just merged main, should be good to go if CI is green

Watcher tests seem to be failing right now (maybe an update?), I'll have a look

Nvm, rather it looks like the phpheaders_test (#1823) will still randomly fail builds so I moved it back to frankenphp_test (probably will report this one to go)

Should be fine now 👍 , linting failure is unrelated to this PR.

Thank you! Great work, as usual.
