there might not be a file backing a process, but there is a free form |name|
property that if you squint reads (sometimes) like a path via

 mx_object_get_property(handle, MX_PROP_NAME, name, sizeof(name));

better than nothing ...

Thanks, had a go at that. (This function seems to see very limited use based on
https://cs.chromium.org/search/?q=GetProcessExecutablePath+package:%5Echromiu...
, so I'm not sure if this works or not.)
