There are intermittent failures in the RPC tests, but these failures in
the kadm5 api test suite seem to dominate in the recent runs:

Running ./api.1/lock.exp ...
FAIL: 3: eof while waiting for permanent
FAIL: 9.1: eof while waiting for released
FAIL: 10: eof while waiting for released

Sometimes there are more, sometimes 9.1 doesn't fail, but 3 and 10 in
api.1/lock.exp seem to be failing fairly reliably recently on dcl.  This
is in all four combinations of 32-bit gcc and 64-bit cc compilers, and
static and shared libraries.
