Ulrich,
	I've incorporated your suggestions, wih the exception of passing the 
pthreaad
mutex attribute into the kernel for futex_register.  I'd like to be 
able to
pass the attributes associated with the pthread_mutex into the kernel
so the kernel can support whatever attributes are on the mutex without
having to change the interface between glibc and the kernel.

	If we pass the attributes in for robustness we don't have to change
the interface if/when the kernel supports other attributes, like
priority inheritance.

	Let me know what you think of the implementation, and thanks
for the suggestions, they made the patch much less intrusive.
