"A condition (short for ``condition variable'') is a synchronization device "
"that allows threads to suspend execution and relinquish the processors until "
"some predicate on shared data is satisfied. The basic operations on "
"conditions are: signal the condition (when the predicate becomes true), and "
"wait for the condition, suspending the thread execution until another thread "
"signals the condition."
