Description

This panic only started to occur after the new topology-aware scheduler work was imported.

I can easily reproduce it by running heavy pgbench read-only loads: with 64 client processes,
a dual-Xeon system typically crashes in less than 10 minutes.

A core dump is available on leaf:~ftigeot/crash/crash.lwkt_send_ipiq

This should be fixed in 55b580aea14626bdfa5f22a165b0f1ddf8217cdd now,
please retest!
