Hi, thank you for such a great tool.

The sandbox functionality of gawk is great, but it needs significant 

Even with sandbox, arbitrary files can be read using the following code:





Argument rewriting is an important feature as it allows controlling execution 
(like the example rewind() function).

I would like to propose that a list of original argument paths be used as a 
whitelist for all functions.

It would be ideal to relax the restrictions on the currently sandboxed 
functions as accessing internet resources is a useful feature that would not 
affect the local system.

Bioinformatically yours,
