Comment:

 This bug report is correct.  Stopwatch uses coherent distributed
 algorithms to store all state, and when I added the marks system, my
 algorithm for sets did not support coherent deletion.

 Later, I ripped the algorithms out of Stopwatch and turned them into
 Groupthink [1].  Groupthink then got the upgraded algorithm we need
 (CausalDict).  Therefore, the logical way to move forward with this is to
 port Stopwatch to use the Groupthink library.  I have a lot less free time
 for Sugar stuff than I used to, but I'll plan to do this at some point.
 Nobody else has really used Groupthink, so I doubt that the docs/API are
 even comprehensible.
