It seems to be fine. I can't really say that one is better than
the other. Smoother interactive performance would be nice to see, but
the system was usable during the tests (about the same as 227a3 &
226a2. Here are all the #s for the 50k tests:
test 1 - boot, login & run dbase on a file.
test 2 - boot, login, startx, run dbase on a file, bring up netscape,
edit in emacs, etc.
dbase program builds a gdbm database. See previous msgs for details.
Test 1 (noninteractive) Test 2 (interactive)
