we can't get SYN_DROPPED through uinput, so we push two events down
uinput, and fetch one off libevdev (reading in the other one on the
way). Then write a SYN_DROPPED on a pipe, switch the fd and read
one event off the wire (but returning the second event from
before). Switch back, so that when we do read off the SYN_DROPPED
we have the fd back on the device and the ioctls work.
