[Message part 1 (text/plain, inline)]

Guixfriends,

Errors like the one below are omnipresent.  It's a problem.

Expecting an ever-increasing (16k+?) number of requests to finish 
flawlessly or aborting a very long (20+ minutes here) process is 
doomed.

We don't seem to have a plan forward (I include myself!).  Looking 
at other package managers, a blunt ‘retry a finite number of 
times’ seems common.  Guix's ‘pretend that "transient" is a magic 
powerword’ approach less so.

What do people think?  Does the heavy pipelining complicate 
matters?
