The rule of thumb here is that if it accesses the process's memory, it
isn't supported for remote procseses.  Affects:

cmdline
environ
exe
maps
mem
statm

stat and status are partly supported.  The stuff like pid, comm, state
and times are updated from the remote process - although in a somewhat
lazy fashion.  Stuff like signal handler state isn't mirrored fromt he
remote binary.  Neither are any of the memory stats.
