I didn't get to the logs yet, but with this change added I see many do_install tasks failing with exit code '134'.
It might have different cause, but I wasn't seeing this after last oe-core upgrade before this last pseudo SRCREV bump.
There isn't temp/log.do_install* (for whatever reason) and in pseudo.log I see following 3 lines being repeated couple times:
debug_logfile: fd 2
pid 47520 [parent 47518], doing new pid setup and server start
Setup complete, sending SIGUSR1 to pid 47518.
250 times even for very simple recipe:
sysvinit-inittab/2.88dsf-r10$ grep -c "Setup complete, sending SIGUSR1" pseudo/pseudo.log
