bitbake: runqueue: add memory pressure regulation
Prevent new tasks from being scheduled if the memory pressure is above
a certain threshold, specified through the "BB_MAX_PRESSURE_MEMORY"
variable in the conf/local.conf file. This is an extension to the

48a6d84de1 bitbake: runqueue: add cpu/io pressure regulation
Memory pressure is experienced when time is spent swapping, refaulting

memory pressure is rarely seen but might be useful as a last resort to
