10.4, 10.5, 10.6
Description
Note: I do not normally compile or test Spider. This time I did, on 10.4. The test failed in a 32-bit RelWithDebInfo build. It turns out that the test is nondeterministic, because I also got it to fail on a 64-bit Debug build, with enough retries:
./mtr --parallel=auto --repeat=100 spider/bugfix.wait_timeout{,,,,,,,,,,,}
|
Here are two sample failures:

Please try to fix this in the earliest applicable version. I did not check any other source code revisions than 10.4e2f1f88fa60680cb87833a7cceb172f5d436a804 .
