In documentation and comments, be more like POSIX in terminology involving multithreading. Explain the distinction between multithreaded process vs multithreaded program. Change “program” to “process” when the latter wording is more accurate or informative. Simplify the wording for the constraints on processes that use unlocked I/O. Change “multithread-safe” to “thread-safe”. Change “thread-safety” to “thread safety”. However, do not change “multithreaded” to “multi-threaded” even though there are some uses of both spellinga, as there are a whole bunch of uses of “multithreaded”, also in identifier names; perhaps Gnulib should even standardize on “multithreaded” (not “multi-threaded”), contra POSIX.

This function is missing on many non-glibc platforms:
|
|
glibc 2.9, macOS 14, FreeBSD 6.0, NetBSD 7.1, OpenBSD 3.8, Minix 3.1.8, AIX 5.1, HP-UX 11, Solaris 11.3, Cygwin 1.7.1, mingw, MSVC 14, Android 4.4.

But the replacement function is not atomic; this matters in multi-threaded
|
|
processes that spawn child processes.

SOCK_CLOEXEC and SOCK_NONBLOCK may not be defined
|

as they're also significant to the socket() function.
