The problem here was the run-debuginfod-find.sh testcase timeing out
under valgrind. The way curl does hostname lookups in multi_curl mode
seems to take minutes under valgrind (it keeps retrying). But the only
lookups in the testcase are for localhost. By simply replacing
localhost with 127.0.0.1 the time to run this testcase under valgrind
locally goes from 10 minutes down to 3 minutes.
I have committed the patch below and will monitor whether all buildbot
workers will now succeed.
Cheers,
Mark

Subject: [PATCH] tests: Use 127.0.0.1 in run-debuginfod-find.sh instead of
localhost.
The way curl does hostname lookups in multi_curl mode takes a very long
time under valgrind. Replace all localhosti hostnames with 127.0.0.1 so
no lookups are necessary.
