Description
Keeps the thread in a busy waiting status until the specified condition is satisfied or until the specified timeout expires.
There are three overloaded SpinUntil methods. All three have a generic parameter, ACondition, whose type is a Boolean function. The second and the third methods have an additional parameter, Timeout, of LongWord type and TTimeSpan type, respectively.
