Initial Insall/Build of latest srsRAN - "make test" chews up CPU and breaks TCP/IP connection

[dcrowleyMunster]

In running through the initial install steps and compiling from source (srsRAN):
- when running the "make test" step, the process would get to a maximum 787 tests and then the server dropped all TCP/IP and the "make test".
- Running "top" showed "make test" chewing up CPU and then process drop followed by network
connections dropped.

My fix was simple, please see below - If anyone else sees this issue, lower the process priority on the CPU
