For one, you should only use async-signal-safe functions after fork(),
until
you exec().

This is wrong. You are probably talking about vfork().
This is why there is pthread_atfork.

A process shall be created with a single thread. If a multi-threaded process
calls fork(), the new process shall contain a replica of the calling thread
and its entire address space, possibly including the states of mutexes and
other resources. Consequently, to avoid errors, the child process may only
execute async-signal-safe operations until such time as one of the exec
functions is called.
