Comment(by Sergey Samsonik <serge_98_at_[hidden]>):

 This is not a showstopper for me any longer since the systems I'm working
 with now (CentOS/RedHat 4.5+) implement Posix shared mutexes, even thought
 /usr/include/bits/posix_opt.h states it otherwise. There's another
 /usr/include/'''nptl'''/bits/posix_opt.h header, which defines correct
 values for these systems. -I/usr/include/nptl compiler option addressed
 the problem in this case.

 I don't know it it's possible or how, a solution (at least a temporary
 one) may be disabling generic (interprocess) recursive mutexes on systems
 where thread ids are not unique.

 Also, the problem looks very similar to the one in ticket #1390 here.
