Get Redbean fork() working on the New Technology

Browse source 
Now that we have understandable system call tracing on Windows, this

help things get closer to tip top shape. Support for complex forking
scenarios had been in a regressed state for quite some time. Now, it
works! Subsequent changes should be able to address the performance.
