It makes sense to use gslice for all small allocations IMO.  For things
like your usecase that you are freeing the memory very very soon, there
may not be any memory fragmentation worries.  So the benefit of gslice
here would be speed on systems that have a slow malloc.

Thinking about it now, better would be to use a stack buffer for small
n_args values, like 8 for example.
