See NSLock for more information about what a lock is. A recursive
|
|
lock extends NSLock in that you can lock a recursive lock multiple
|
|
times. Each lock must be balanced by a cooresponding unlock, and the
|
|
lock is not released for another thread to aquire until the last
|
|
unlock call is made (cooresponding to the fist lock message).

|
|
Attempts to aquire a lock before the date limit passes. It returns
|
|
YES if it can. It returns NO if it cannot
|
|
(but it waits until the time limit is up before returning NO).
