Bug Description

with lp:mir, running:

tools/detect_fd_leaks.bash valgrind --trace-children=yes --leak-check=full --show-leak-kinds=definite --errors-for-leak-kinds=definite --track-fds=yes --num-callers=128 nbuild/bin/mir_acceptance_tests --gtest_filter="ClientCredsTestFi*"

alongside
stress -c 12 -i 3

can produce a failure like:
Note: Google Test filter = ClientCredsTestFi*
[==========] Running 2 tests from 1 test case.
[----------] Global test environment set-up.
[----------] 2 tests from ClientCredsTestFixture
[ RUN ] ClientCredsTestFixture.session_authorizer_receives_pid_of_connecting_clients
unknown file: Failure
C++ exception with description "Poll on readfd for pipe timed out" thrown in the test body.

and, if running under CI, will time-out, and report a fd leak.

Just a timing/racing problem? Or related to bug 1483097?

This bug has the same underlying cause as bug 1570353 (but the manifestation is different), namely that under high load valgrind is excessively slow and the timeout for starting the server is exceeded.

      . [regression] unity8 fails to start when built with 0.24 series (lp:mir)
        (LP: #1597717)
      . CI failure in MirSurfaceVisibilityEvent.exposed_received_when_surface_
        raised_over_occluding_surface [called twice - over-saturated and active]
