/* Oh, what a hack. If we're trying to perform an inferior call
while the inferior is asleep, we have to make sure to clear
the "in system call" bit in the flag register (the call will
start after the syscall returns, so we're no longer in the system
call!) This state is kept in "inf_status", change it there.
We also need a number of horrid hacks to deal with lossage in the
PC queue registers (apparently they're not valid when the in syscall
bit is set). */
