>Description:
NetBSD doesn't currently support pthread process shared synchronization
primitives.

in these days of many cores/CPUs applications programmers would appreciate
these and it would even enable some of us *cough* to move applications off
linux to NetBSD.

Pretty please make our sysconf(3) return 200112L for
_POSIX_THREAD_PROCESS_SHARED. but unlike apple did with MacOS X Leopard
actually implement the support instead of just claiming implementation
that doesn't exist. :)

>How-To-Repeat:
	200112L != sysconf(_POSIX_THREAD_PROCESS_SHARED); --> :(

	0 != pthread_xxxattr_setpshared(&attr, PTHREAD_PROCESS_SHARED) --> :(
>Fix:
	200112L == sysconf(_POSIX_THREAD_PROCESS_SHARED); --> :)

	0 == pthread_xxxattr_setpshared(&attr, PTHREAD_PROCESS_SHARED) --> :)
