Description
I encounter this one while using the ocaml package manager to install some package:
strace -a ~/.opam/4.14.2+trunk/bin/dune exec -p lwt src/unix/config/discover.exe -- --save --use-libev true
==> [ 82079] exec = 0x8000000f Operation not allowed (22 us) Error: execve(./_build/default/src/unix/config/discover.exe): Operation not allowed
It seems exec_team() is called from non main thread.
I tried to submit a patch to that effect https://review.haiku-os.org/c/haiku/+/7105, but after discussion with waddlesplash, the best solution would be to change the main thread , and not steal its id. This is way before my head.

for help on using tickets.
Linux does the following: the main (leader) thread is terminated, and the non-main thread assumes its identity: https://elixir.bootlin.com/linux/v6.6/source/fs/exec.c#L1081
