Well, a full libc FFI wrapper would be useful... Something that pretty much any other language provides out-of-the-box. Something familiar for developers that are new to our community perhaps.

Lol. Just to mention that we have been having problems (VM crashes/lockups) with OSProcess, using FFI to callout to libc for executing shell command has seemed to help this. Looked like memory corruption (especially targetting Delay objects, but likely they were on the stack at the time...). Occurs on all VMs, though more apprent with Cog. FFI saves the day!
