That's what the ExecTimeout option is for: mitigating the time it takes to
execute the requested command.  The assumption is that mod_exec would be
used for synchronously executing commands that might affect the session
(files uploaded by the user get moved, etc).

Yes.  For FIFO-based logging, all that the session process cares about is
having write() return; whether the FIFO process on the other end of the
write() performs an action synchronously before returning, or
asynchronously performs the action after return, is opaque.
