Description
When St/X is started without access to graphical environment it enters a REPL. In Windows REPL causes high CPU usage.
It seems that for whatever reason St/X keeps polling for I/O which is what burns the CPU. Note, that in order to reproduce this you need to run St/X in a way that it has no access to Winsta0 window station. One way to simulate this is to hack WinWorkstation>>primInitializeFor: to always return nil
