--- According to KH os.execute is not permitted in plain/latex so there is
--- no reason to use the normal context way. So the method here is slightly
--- different from the one we have in context. We also use different suffixes
--- as we don't want any clashes (sharing cache files is not that handy as
--- context moves on faster.)
---
--- Beware: serialization might fail on large files (so maybe we should pcall
--- this) in which case one should limit the method to luac and enable support
--- for execution.
