Michael Kerrisk 39720f03eb dlsym.3: ATTRIBUTES: Note functions that are thread-safe 
After research, We think
* dlsym(),
* dlvsym()
are thread-safe. But, there are not markings of them in
glibc document.

* dlmopen(),
* dlclose()
are thread-safe. But, there are not markings of them in
glibc document.

Michael Kerrisk 43151de329 ldd.1, sprof.1, execve.2, dlopen.3, ld.so.8: Prefer "shared object" over "shared library" 
The man pages variously use "shared library" or "shared object".
Try to more consistently use one term ("shared object"), while
also pointing out on a few pages that the terms are synonymous.
