If it's a short list, then it's a short list.

Because we are not working in a vacuum. A thread-safe implementation of
libpq is of zero value to an application unless it also has thread-safe
implementations of the other libraries it depends on. When the
platform's libc has more thread-safety holes than the average block of
swiss cheese, there is no reason that I can see for us to expend effort
on workarounds that only fix libpq's usage. Any app that might want to
use libpq is going to hit those same bugs, and so in the long run the
only useful answer is for the platform to fix its libc.
The real bottom line here is: who is going to try to build threaded
apps on platforms with un-thread-safe libc? And why should we be the
ones to try to save them from suffering the pain they deserve? We have
enough problems of our own to deal with...
