mirror_exit minus mirror_replace was kept in the BH because it's not safe to
call in coroutine. After discussing with kwolf o
Commit 5a7e7a0ba moved mirror_exit to a BH handler but didn't add any
protection against guest requests that could sneak in before the BH is
dispatched. For example, this could happen (assuming a code base at that
commit):
main_loop_wait # 1
os_host_main_loop_wait
g_m
