I'd guess that this is as expected. Firebird uses it's own thread
scheduler. Although, I don't know about the NPTL build. If your
linux kernel supports NPTL, you might want to try the NPTL build.

Other than trying the NPTL build, if you can, I recommend using
Classic Server, instead of Superserver.
