AFAIK no. More precisely, at startup sbcl core processes
arguments, includingrequest for memory allocation. At
this point one can give argument requesting different allocation.
However FriCAS uses sbcl ability to create executables.
IIUC in executable core arguments are either all hardcoded or
all given on command line. Currently we need to hardcode
some arguments, which in turn means that all are hardcoded.

Yes.

One can specify '--dynamic-space-size' argument during _sbcl_
build to get different default.a After that executables
build using this sbcle will have different memory allocation.
