This started to happen on build 199 https://build.webkit.org/builders/GTK%20Linux%2064-bit%20Release%20%28Perf%29/builds/199

Several tests fail https://build.webkit.org/builders/GTK%20Linux%2064-bit%20Release%20%28Perf%29/builds/199/steps/perf-test/logs/stdio

The exact tests that fail change from run to run. 



My initial suspect is the GLib/GLib-networking upgrade in r215556 <https://trac.webkit.org/r215556>.
I will try to reproduce it locally and see if I can confirm this.
