i don't know if we can allow disabled gcs thread creation with locked gcs state. (i can see arguments both ways, so further prctl flag may be needed which may be another divergence from x86)
I think that if we do add a new flag that'd just be new functionality, the divergence would be in allowing configuration via clone3() rather than the flag. TBH I'm not sure I see a use case for locking but providing a mechanism for getting out of the lock, that seems very questionable.
