Bugzilla Bug 137981

I usually start my KDE session with one konsole but with around ten tabs open
on it. I only want keychain output to come up on one so looking at the options,
I saw the --lockwait option.

   --lockwait seconds
       How long to wait for the lock to become available. Defaults to 30
seconds.

If it is locked I don't want to bother waiting at all, so I set lockwait to 0,
meaning wait zero seconds, don't wait at all. 

After a few unsucessful attempts (an infinite loop waiting for the lock), a
quick look at the script shows that using a value of zero for the seconds seems
to mean wait indefinitely for the lock, rather than waiting zero seconds. Is
this the correct behaviour (as in expected). If so, maybe a comment to this
effect in the man page or help output would be appropriate.

Good point.  0 was supposed to mean forever, but it makes more sense to use -1
for that and let 0 return immediately.

Fixed in 2.6.6
