Here is the relevant section from H.J. Lu's release notes:

Would someone like to test the pthread library that is built? You'll
need to get the libc5 source and recompile the entire package
yourself. If libpthread proves to work, I'll include it in either the
next libc5 package or a separate libpthread package.

For stability. Libc 5.3.12 was brand new when we first started
preparing to release Debian 1.1.
