[svn-r14104] Description:

	Pursue calls to H5Gcreate() relentlessly and ruthlessly exterminate
them, leaving only a few tame specimens in text files and comments.  ;-)

Tested on:
	Mac OS X/32 10.4.10 (amazon)
	FreeBSD/32 6.2 (duty)
	FreeBSD/64 6.2 (liberty)
	Linux/32 2.6 (kagiso)
	Linux/64 2.6 (smirom)
	Solaris/32 5.10 (linew)
