i have come across this and have no idea if it might be helpful but hth
http://www.coda.cs.cmu.edu/doc/talks/linuxvfs/tsld021.htm
or http://www.coda.cs.cmu.edu/doc/talks/linuxvfs/index.htm

and answer to subject... one way to get orphaned inodes probably is:

	one process opens file and keeps sleeping forever or cycling
		while still having the file opened
	another process deletes/unlinks file ()and on exit immediatly 
		powers off or reboots or you switch the power off...

some side effects probably included
