Make the number of threads variable for valgen #22
Description
Is your feature request related to a problem? Please describe.
Currently the number of threads we use for valgen is 8. Maybe some people don't want to use that number.
Describe the solution you'd like
A way to configure at valgen runtime the number of threads valgen should use. Prolly a command-line argument.
Describe alternatives you've considered
The software could default to using half the cpu total thread count. In fact, that's a good idea for a default if nothing's on the command line.
