to test this fix is necessary to use knet_bench or corosync with openssl
and lots of heavy load (perf benchmark) workload. Sooner or later
the application will crash with some random tracebacks.
after this patch, the crash cannot be reproduced anymore.
tested using 9 nodes x2 active/active links all running corosync + cpghum
