FWAIT

       Logic:      80x86 wait

     FWAIT causes the 80x86 microprocessor to wait until the current
     80x87 instruction is completed. It is used to synchronize the 80x86
     and 80x87.

     FWAIT is the same instruction as the 80x86 WAIT instruction.
     However, you should use the FWAIT instruction since WAIT may cause
     an infinite wait under some circumstances.

        Note:          Whenever FWAIT is required in a program, assemblers
                       usually insert one automatically.
