1. Report it here, for me to investigate. -> Thanks!
2. This seems to be a Linux kernel, which uses only a limited portion of the said
   address range. => No worry.
   Whereas on OpenBSD, the memory mappings are statistically distributed across
   the address range. In this case, NO_ADDRESS_SPACE_ASSUMPTIONS must be set
   (already done in lispbibl.d for OpenBSD).

When I'm back to clisp development (currently I'm preparing libffcall 2.0), I plan
to solve this issue by
  - not defining SINGLEMAP_MEMORY on Linux,
  - instead use TRIVIALMAP_MEMORY (otherwise we lose the generational GC) with a
    range that is determined through some improved heuristics.
