tinkering with this, I've not yet retrieved the exact error message and
I'm interested in seeing what happens if the .so itself tries to use
libdl to reopen the main program.

Can such an alternative entry point in the main unit be called by
a shared library, i.e. either resolved at load time or with the main
binary reopened like a library? Or is the only way to pass a main-

program invocations (i.e. two programs using the same shared library
wouldn't clash)?
The discussion of libraries in ch16 of the Language reference guide is
rather quiet on the semantics.

I'm currently tinkering with shared libraries, using cmem, mainly on

I'm not moving data between threads inside the library.
Am I correct in believing that unit-level variables in a shared library
for an embedded system, but have
never tried exploiting it with a real OS.

best debugs operation as control is transferred from the main
program into the shared library, bearing in mind that this might be
important since the library might have all the tricky code.
