Hi,

Hmm.  I was going to say that the likely problem is that code from (gnu
machines hetzner http) gets inlined so you cannot really mock it.

To make sure this can be mocked, you can use this trick:

  (set! proc proc)

where ‘proc’ is the procedure you want to mock (that statement prevents
the compiler from inlining it).
