Draft: pthread_create, RT scheduler, and address sanitizer are incompatible in Ubuntu 18.04+

When we run with the RT scheduler and the address sanitizer in Ubuntu 18.04, pthread_create will hang and never create threads. Due to this bug, we do not run as real time when the address sanitizer is enabled. This is logical because when you are running with the address sanitizer enabled, performance is obviously not important, therefore the real-time performance is likely not significant.
