The classic EVA-requiring emergency is being unable to get the cargo bay
doors closed properly.  There is a hand-crank procedure for emergencies.

Various other possibilities arise when deploying one satellite and picking
up another.  As seen on the Solar Max repair and the Palapa/Westar retrieval,
the nifty gadgets don't always work.  As seen on the P/W retrieval, the
Syncom repair, and the Skylab solar-array deployment, human muscle and
simple tools are much more robust in the face of trouble.  (As demonstrated
by Nelson, brute-force improvisation doesn't always work.  As demonstrated
by Volkov, sometimes it *does*.)
