Feature request: Implement Kernel.exec

[geoff-nixon]

I was looking for a way to add Kernel.system, Kernel.`, to mruby/mruby, and eventually I found mruby-xquote and mruby-syscommand, but then I remembered your fork, and it seems you have these! But I am having trouble finding the code where this is implemented. (I don't think you're using those mgems...)

Could you kindly show me where this code is?
How difficult do you think it would be to implement Kernel.exec as well?

We divided iij/mruby into many mrbgems (list of them is on README.md). Our implementation of Kernel.system was moved to https://github.com/iij/mruby-process and Kernel.`` was moved to https://github.com/iij/mruby-io . We don't have Kernel.exec` but I think it would be easy.

Awesome, thank you! Yes, I did see the list of your mrbgems (which are great!), but I was confused, as I thought mruby-process/mruby-io would only contain items from the Process/IO method/class.

Unfortunately, the MRI code for Kernel.exec differers from Kernel.system more than I thought, and my [lib]c skills are not up to the task.

So can I politely turn this into a feature request for Kernel.exec in either mrbgem, that would be awesome.

Also, it might be worth documenting that these (and perhaps there are other miscellaneous modules?) are in these other mrbgems for people like me.

FWIW I think @jkutner was working on this: jkutner/mruby-process@82f70ac

I was but I need more windows support, so I ended up rolling my process execution code into mruby-jvm.
