To those with UBC3 problem and wishing for more to go on:
Enable full debugging by setting the environment variable "export
DEBUG=5". (Works for all 2.x branches, maybe?)
Send debugging messages to stderr with "export MSGD_OPTS=-s".
These break 'runtests', but if run on a known problem runtest, these can
help. (Fixing 'runtests' to handle higher debug levels was non-trivial,
IIRC.)
