A race condition in the subgraph executor, could cause a subgraph to be launched slightly too early.
The consequence was that the master sent the subgraph to the slave too early and it was queued and never ran and the master would be blocked waiting for a response from the initializing graph on the slave (that would never come).
After a long timeout an "Timeout receiving from slaves after graph sent" would be reported.
