     * intrinsics. The behavior is that non-initial key events associated

You are quite right. There are many problems with the translation
manager handling of multiple event left hand sides. This is mostly due
to the fact that a single table is used to do both caching of event
matching information and lookup ordering of both initial and ensueing 
incoming events. We (HP) are in the process of rewriting the translation
manager for much improved data space usage with a byproduct being (hopefully :-)
correct handling of event sequences and table merges (another problem area
in the current implementation). We will be donating this code to MIT in the 
next few months. Depending on timing and release decisions it should be
available by R5 (if not sooner).

Please also send bug reports related to the tm to xbugs@expo.lcs.mit.edu so 
that they can be logged and checked against any proposed implementation changes.
