Mark Johnston b7eae75807 Make sendfile(SF_SYNC)'s CV wait interruptible. 
Otherwise, since the CV is not signalled until data is drained from the
socket, it is trivial to create an unkillable process using
sendfile(SF_SYNC) and a process-private PF_LOCAL socket pair.  In
particular, the cv_wait() in sendfile() does not get interrupted until
data is drained from the receiving socket buffer.
