Re: Making Threads Wait for Other Thread's Results

Some more information on this:

The function nmap.mutex will take an "object" parameter. This can be
any data type except nil, booleans, and numbers. This is to provide a
large degree of flexibility (as I see these mutexes can be used for
many things). The function returned by nmap.mutex will have four
different options associated with it: "lock", "done", "trylock", and
"running". Lock is a blocking lock on the mutex. "done" releases the
lock on the mutex (errors if you do not have the lock). "trylock" is a
non blocking lock on the mutex; it returns true if you got the lock
and false otherwise. "running" returns nil or the thread currently
locked on the mutex. "running" should only be used for debugging as it
interferes with finished threads being properly garbage collected.

Cheers,
