Looking around, I found it is likekl related to our usage of mitogen in IDR rather than the role itself - see mitogen-hq/mitogen#832.

Looks like this has been addressed in mitogen 0.3.4 and we are using 0.3.3 so unless you object, I'd propose to
1- fetch the last tags in /~https://github.com/ome/mitogen
2- bump our submodule to use mitogen 0.3.4
3- see if the deployment goes beyond this task
