Downside is it's weak performance that renders it pretty much a CS > only thing. Dekker's Algorithem and Lamport's Algorithm are not match for test_and_set() interface in glibc. In test_and_set(), mutex var is INT, but those algorimths need to share addtional variables. --- Hiroyuki Machida Sony Corp.
