Indeed. We'd had a discussion about getting a dump of threads
using sysrq (or similar), given the challenges around actually
getting a crash dump, is that now possible? That will certainly help.

another missing bit is that we still need the sychronize_net()
in rds_release(). I realize synchronize_net() is sub-optimal for perf, 
but leaving this existing hole where races can occur in unexpected
manifestations is not ideal either.
(See for earlier
discussion thread)
