[Bordeaux-threads-devel] CONDITION-WAIT with timeout

[James M. Lawrence]

I have added a :timeout option to condition-wait.

git pull https://github.com/lmj/bordeaux-threads

Tested on ABCL, Allegro, CLISP, Clozure, ECL,  LispWorks 6.1, and SBCL.

I don't have SCL, but if the documentation is correct then it should be OK.
