        Could someone with more experience then I have, please explain
how a math co-proc. is handled under any System V os???  What I want
to know is, if two tasks want to use a 387 is the math unit treated
as a resource that gets locked and unlocked?  If not is the data
in the math co-proc. switched during a task switch, and if this is
true isn't this slow!!!!!
