Typo-fix: s/looses/loses/g

When an archer lets go of the bow-string, she looses an arrow; when
the hounds are straining at their leashes and the handler lets go, he
looses the dogs.  It's archaic usage now; we'd normally say "lets
loose", "lets go" or "releases".  In any case what was meant here was
that something got lost; a widget loses focus or a network loses its
connection.
