344	Heavily loaded host systems may crash Multics with a PRDS stack overflow.	canthony	Eric Swenson	"When running CI-kit on some heavily host systems, occasional ""Fault in idle process"" or "" Fault/interrupt while on prds"" sys$trouble crashes were observed.

This was determined to be a race condition in Multics triggered by the inability of the simulator to fairly allocate host cycles to the different simulated CPUs.

Details of the analysis are attached as ""PRDS stack overflow.pdf""
