Comment 2 Jason Lawrence 2020-04-02 08:26:34 PDT 
I can reproduce the issue on r259384 with the command below. 
run-webkit-tests --iterations  99 --exit-after-n-failures 10 --force -f --exit-after-n-failures 3  http/tests/workers/service/basic-timeout.https.html

[4/99] http/tests/workers/service/basic-timeout.https.html failed unexpectedly (com.apple.WebKit.Networking.Development crashed [pid=8102])
[5/99] http/tests/workers/service/basic-timeout.https.html failed unexpectedly (com.apple.WebKit.Networking.Development crashed [pid=8103])
[6/99] http/tests/workers/service/basic-timeout.https.html failed unexpectedly (com.apple.WebKit.Networking.Development crashed [pid=8118])
Exiting early after 3 failures. 3 tests run.
0 tests ran as expected, 3 didn't (96 didn't run):

r259383 results:
All 99 tests ran as expected.
