This issue is a property of the userland though -- Debian
GNU/kFreeBSD's using glibc and friends, not the FreeBSD userland.
In FreeBSD 11.0-CURRENT we no longer have the limitation that
libpthread must be loaded at startup. I tried the sample code attached
to the sourceware PR (with two trivial changes to get it to build on
FreeBSD) and it does not encounter any misbehaviour.
I haven't looked at the implementation of any related functionality,
though, and I'm not certain there aren't other, similar problems
lurking in FreeBSD.
