    - add <heartbeat_debug> log flag
    - show trickle-up and int file upload msgs if <app_msg_receive> set
    - if scheduler RPC reason is trickle-up, say so
- manager:
    - restore "non CPU intensive" to task description
    - project properties: show if RPC in progress or trickle-up pending.
        (show these low-probability things only if present)
- manager: fix Unix build
