Detailed Description

FXReadWriteLock allows multiple readers but only a single writer.

FXReadWriteLock provides access to a shared region just like FXMutex, except that threads that just read from the shared variables are not excluding each other. When a thread tries to write, however, it can only proceed when no other writers or readers are present. Thus, data structures which are frequently inspected but rarely updated can be more effectively accessed with a read/write lock than with a mutex.
