The revisions merged are: alpha/lockdflt.c: 1.5 -> 1.6 i386/lockdflt.c: 1.5 -> 1.6 I discussed this merge with the release engineer and we agreed that this particular merge would best be done as soon as possible, rather than waiting until just before the 4.1 code freeze when it couldn't receive the benefit of testing with the ports it is intended to fix. (It should fix Mozilla and other user threads based programs. And it should fail to break any linuxthreads based programs.) Approved by: jkh Notes: svn path=/stable/4/; revision=63370
