Yes, but only in -batch sessions.

I believe this is our logic now: if we are going to compile a
trampoline, we invoke an async subprocess with both -batch and
the -no-comp-spawn options.  But if the --batch session can figure
out that it's compiling a trampoline, it can automatically behave as
if -no-comp-spawn was passed on the command line, no?

I'm asking why compilation of trampolines could behave like that
automatically, when the compilation is done in a -batch invocation.

Thanks.
