Thanks, that makes sense.
The block manager stuff seems to be pretty self-contained. The only data
included in the block manager heartbeat is the block manager ID, and the rest
of the block manager RPCs concern block-related happenings. So my inclination
is to not muck this up with task data and to add a general heartbeat actor.
