Looks OK to me (tho this `dolist` in the middle of all those
`(tramp-accept-process-output .. 0)` busy loops is definitely not the
most efficient use of resources :-).

PS: An unrelated comment, is that `shared-socket` and `vector` should be
renamed to clarify that these are properties specific to Tramp processes
(i.e. use a `tramp-` prefix).
