Todd Lipcon commented on KUDU-3131:
-----------------------------------
I can confirm I'm able to reproduce this on Ubuntu 18.04 x86 as well
(deadlocked after 17 iterations of rw_mutex-test).
Perhaps we should consider our own rwlock implementation, or at least file on
upstream Ubuntu bug tracker to request a backport (seems there is discussion in
the above linked ticket)
