I am curious about what **MT-Safe** means exactly here. 

For example, this function https://android.googlesource.com/platform/bionic/+/android-4.2.2_r1/libc/bionic/tdestroy.c is clearly not to be called concurrently on the same tree, while POSIX and [this manpage](https://man7.org/linux/man-pages/man3/tsearch.3.html) claims it is **MT-safe**.
