[Axiom-developer] Calling gbc before init-memory-config in restart (bookvol5)

[Vanuxem Grégory]

Hello,

What about "garbage collecting" (gbc t) in the 'restart' function
(bookvol5) just before calling 'init-memory-config'.

In fact I can not load more than 16 libraries in .axiom.input when I
call 'restart'. These libraries are not completely loaded, just some
')lib something'. I obtain this error:

   >> System error:
   Can't set the limit for relocatable blocks to 1000.

but if I issue (gbc t) before calling 'restart' that works.

Here is the output of 'room' if I do not call 'gbc'. No operation has
been performed, just 16 ')lib':

If I issue a (restart) I get the error above but if I "garbage collect"
the output of 'room' is:

  2110/3000               1 contiguous (274 blocks)

    494771 pages available
     21278 pages in heap but not gc'd + pages needed for gc marking
    524288 maximum pages

And I can call 'restart'.

I tested to increase the number of relocatable blocks with
(init-memory-config ... :rpages 2000 ...) in 'restart' but this does not
solve the problem, I encounter the same problem later (after calling
'restart' 4 times).

This request is specific and not really important, it's just for
convenience (and I will not need to maintain a patch :-).
