This is probably the most involved of all the changes to get into glibc 
(and also the one most liable to complicate merges from glibc, while any 
such merge into glibc is underway - it would be a very good idea for 
anyone merging such changes into glibc also to take on the task of, after 
each bit is merged into glibc, revising the version of that option group 
in EGLIBC to match changes made in the course of merging it into glibc, to 
avoid complicating subsequent general merges from glibc).

It still appears to be the case that the man-pages project does not have a 
manpage for pthread_mutex_init / pthread_mutex_unlock (the one in 
question), and that Linuxthreads is being used to provide a manpage for 
those functions by Ubuntu, for example.  I believe it is also the case 
that Linuxthreads is still being used by GNU/kFreeBSD, so if that gets 
merged to glibc then there may be a case for merging in the Linuxthreads 
history.

It is indeed the case that NPTL documentation is lacking in the glibc 
manual (glibc bug 6039).
