Yes, this is bit more difficult because most of the commands work
asynchronously.  I changed slime-start-and-load a bit so that it
should be usable for your needs.  

In general If you need commands of this sort, it's usually the easiest
to write a small CL function for the job, so that Emacs can make a
single RPC and doesn't need so much synchronization.

Can't help you here without more details.  Which Lisp are you using?
Which communication style?  Are threads involved?  We don't set
*READ-DEFAULT-FLOAT-FORMAT* explicit, but there's always the
possibility for bug and that we used WITH-STANDARD-IO-SYNTAX in a wrong
place.
