Exceptions not caught properly (1.8.7?)

[timjnh]

Not sure if this is a version difference in Ruby but the rescue clause at line 42 of test_unit.rb does not seem to be catching all exceptions properly under 1.8.7. Currently it reads:

rescue => e

which does not appear to catch MissingSourceFile exceptions. Changing the line to

rescue Exception => e

resolves the problem. Not sure if this patch would introduce other issues.
