I saw that it is possible to boot Julia with up to 2 sysimages by using the `-J` argument.  
I was wondering if it possible to do the same thing programmatically in C?  
I did not see any options other than `jl_options.image_file`, to pass one single sysimage before initialisation. Is there any plan to implement this feature through the C API?

Thank you !
