man getservby name says:
"Attention: Do no use the getserbybyname routine in a multithreaded
environment"
Is there a list of such routines or a checker that allows to scan
programs and check for usage of non-threadsafe routines?

1. glibc2: reentrancy, thread-safety, signal-safety
I have heard that glibc2 is close to thread-safe. Does anyone know how
thread thread safety is implemented. Does thread-safety mean signal-safety
that is: I can use --say-- malloc() both in the main process-flow code and
in signal handlers. I suppose it would fairly simply to enforce
thread-safety by using library owned mutexes or critical sections. But this
would preclude signal safety because of potential deadlocks.
By the same token, does anyone know how reentrancy relates to thread-safety
and signal-safety.
Thanks.
