Comment:

 Hi wagon, I'm gonna toss this over to tor and repurpose it to be for
 paginated GETINFO commands. You're right that commands like 'GETINFO desc
 /all-recent' provide megabytes of data.

 These GETINFO commands were created in tor's early days when the consensus
 was pretty small, but nowadays the response of this method is massive. The
 usual way of dealing with this is to have a paginated API where the caller
 can provide a starting index and number of responses. This would let Nyx
 fetch smaller batches without hosing the control connection.

 Unfortunately without that there's not much I can do on my end.
