[ts-gen] Hooking into shim directly via C/C++

[Ken Feng]

Hi Nils,

I am glad to hear that you were able to get this to work!

Would you care to share your code/invocations or at least show us some
pseudo-code of what you did?  Did you popen() and then fork() your
process?  What did you do to resynchronize the two processes, if you
needed to wait for a process to complete?

Any hints would be greatly appreciated.
