In the FAQ it suggests that if interrupts occur at a high frequency that
you should consider installing a real mode interrupt handler in addition
to the protected mode handler. At the same time it states that a DPMI
host always passes the int to prot. mode first, and only if unhandled
does it pass it to real mode. So how does installing a real mode handler
speed anything up? Even if you are temporarily in real mode (calling a
DOS function), the interrupt still goes to pmode first, no?
While we're on the subject, is there any reason that enable() and
disable() aren't inlined in the header file?
Thanks.
