Bug description:
SRU justification:
Impact: When running the test-local-(lxd|docker) tests, the long data
test is sending two pieces of data. In some rare cases it was observed
that the second send was succeeding while the receive side was not
completely closed down after getting the first part. This broke the
test sequence and ended in both master/slave being stuck in waiting
for data.
Fix: Adding a short delay after each successful send avoids this
issue. While being on this, also fixing the direction of the repeat
counter (was counting up instead of down).
Testcase: running the dep8 tests for the ubuntu-fan package.
Regression risk: low (and limited to test functionality)
