Comment 2 for bug 1760827

The patch #1 is naive because it is doing some work already done in %CONDITION-WAIT and because it may not be solving some on all levels. For example, the FIXME in %WAIT-FOR-MUTEX could probably lead to a similar issue.

A serious patch will use the remaining time values computed and returned by %CONDITION-WAIT and lower-level calls.

Probably timeouts have to be treated like deadlines, having both an absolute and relative component. Merging the timeout and deadline concepts might simplify some code.
