//  NAME
//     Delay -- pause for N milliseconds
//
//  SYNOPSIS
//     void Delay(DWORD dwMsecs, BOOL bBlocking)
//
//  DESCRIPTION 
//     Delay pauses for the number of milliseconds specified by dwMsecs.
//     If bBlocking is FALSE, messages in the message queue will
//     be processed.  If bBlocking is TRUE, the message queue will
//     not be processed until the delay period is expired.
//
//  RETURN VALUE 
//     None.
