This still uses testbench-busybear.sv
I think it might be time to finally rename nearly 'busybear' thing to 'linux'

busybear testbench updates
...
start speculative checking on CSR* satp, *
add some slight delays in some CSR checkings to make them deterministic
I realize this verilog is incredibly un-idiomatic. But I still don't
know of anything better. If you figure it out, please let me know
