... BTW, I don't quite see what the issue is there.  The snapshot is
exported from the master session, so errors in worker sessions should not
cause such failures in other workers.  And I don't see any such failure
when setting up a scenario that will cause a worker to fail on Linux.
The "invalid snapshot identifier" bleats would make sense if you had
gotten a server-side error (and transaction abort) in the master session,
but I don't see any evidence that that happened in that example.  Might be
worth seeing if that's reproducible.
