Any direct user interaction in src/frontends/*, worker methods that can
run unattended, possibly bailing out on error in src/{!frontend}. If
errors are non-fatal they could be accumulated and returned or signalled
individually to the gui using a signaling mechanism that does _not_
require the existence of an "observer" (gui or lyxserver)
