It looks like glibc 2.30.9000-18 introduced clock_nanosleep which Chromium's sandbox doesn't allow, causing immediate renderer process crashes.

Background:

• https://bugzilla.redhat.com/show_bug.cgi?id=1773289
• https://bugs.chromium.org/p/chromium/issues/detail?id=1025739

Fix:

• https://chromium.googlesource.com/chromium/src/+/54407b422a9cbf775a68c1d57603c0ecac8ce0d7

I tried applying the commit on 77-based, but chromium/sandbox/linux/seccomp-bpf-helpers/syscall_parameters_restrictions.h doesn't seem to apply cleanly. I didn't investigate further at that point.
