This is a known bug a fix for which I intended to go into
"mcl2.0p1.fasl", but it apparently didn't make it. If you
want a patch, ask me for "import-patch".
The two error messages are correct behavior (though it might be nice
to have a restart that would ignore all the bad imports).
The problem is that there was an extraneous call to the (low-level)
debugger in the restart. The 2 second pause is MacsBug attempting
to find a procedure name near the PC. You can get rid of it with
the "SX" command, which disables that feature.
