Bug #2411: panic: lwkt_send_ipiq: TOO HEAVILY NESTED!

Target version: 


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
