Uw rewrite sync #150

Closed uwiger closed 7 years ago

uwiger commented 7 years ago 
Rewrite gproc_dist:sync() to hopefully be more robust

The old version used gen_leader:leader_call(), which doesn't do well
if the leader dies, or similar things happen. The new solution calls
the local gproc_dist, which remembers the request and casts to the
leader (assuming it's not itself the leader). The leader performs
the sync as before, then casts to the intitial node that the sync
is complete. If a new leader is elected, the other nodes check
pending sync requests and re-initiate them.

Timeouts, which were recently increased, returned to their previous
values.

This may help issue #145

I've restarted the test build five times (10 separate test runs each time, making for a total of 70 test runs), without a single error. This seems promising.
