hello!
it seems that in p-mode, if cpl > iopl, popf instructions are not trapped.
some games like doom and duke3d use popf to reenable interrupts (only when
sb sound is configured) in a sequence akin to this (code runs in p-mode):

  pushf
  cli
  ...
  popf  ; restores if to previous value

under window$ nt this freezes the dos session (virtual interrupts are never
reenabled because popf is not trapped).
my question is: how does dosemu work around this limitation?

thanks,
vlad.
