Be warned, that using index instead of handle to identify interpreter
is not a good way.

All primitives are handle-oriented, an #at: methods simply doing:
HydraVM interpreters at: n.

There is a danger, that when in future i add code to shutdown images,
then indexed can be changed, and thus, code based on indexes might
fail, because
if you having 3 interpreters running:

#(x y z)

and you shutting down 2nd one,
then 'HydraVM interpreters' will return array with 2 handles:
#(x z) , so #at: 3 will lead to error, and #at: 2 will return different handle.
