Implement interruptible wait for messages sent by the kernel
This pertains specifically to handling the IPC_M_PAGE_IN requests
sent by the kernel on behalf of the faulting thread. If the external
pager process does not respond for some reason, the user may decide to
kill the blocked client. That will result in interrupting the client
from the sleep. The kernel will then perform cleanup.
This changeset implements the cleanup by either forgetting the call
(i.e. donating it to the callee) or waiting for the arriving answer,
whichever of the two succeeds.
