It is possible, running under CWSDPR0, to directly manage CPU interrupt
flag via CLI and STI (and IRET, POPF) ?

Are these instruction slow, that is are they trapped by the VM monitor ?

The DJGPP function disable()/enable(), implemented via
dpmi_get_and_disable/enable_interrut(), reflect virtual interrupt state
on the CPU interrupt flag ?

This is an OT question but actually I do not know a better NG for it.

Thanks in advance.
