The only way to have both is fcntl(). So I rewrote all the locking stuff around fcntl(), and used the opportunity to change the interface. The point of changing the interface is to stop having to bother with the old one, so to hell with compatibility, let's just do a major bump. 2017-10-30T12:52:48Z Laurent Bercot ska-skaware@skarnet.org 2017-10-30T12:52:48Z urn:sha1:a22d90e47d420492c98ade168780ba7d3964419b
