One difference I see is that glxgears is linked against libpthread, while
xlock is not.

In the xlock case, the socket() system call is followed soon after by
a connect().  In the glxgears case, the socket() call appears successful
(same positive return value as in the xlock case), but the behaviour
thereafter is quite different.

Try editing xc/lib/Xtrans/Xtransint.h and changing the definition of
XTRANSDEBUG to 5, rebuilding libX11, and running glxgears against that.
This will enable more of the xtrans messages and may help narrow down
the failure point.

BTW, the ktrace for the glxgears in emulation shows it failing because
of not finding libpthread.so.6.0.  BTW, what is this emulation?
