 The issue here is that libgc allocates memory using sbrk, and that seems
 to fail even if psychical memory is available. Perhaps USE_MMAP should be
 defined on linux ?

+Maybe take a look at the tcmalloc from google (code.google.com):
+
+// Configuration parameters.
+//
+// if use_devmem is true, either use_sbrk or use_mmap must also be true.
+// For 2.2 kernels, it looks like the sbrk address space (500MBish) and
+// the mmap address space (1300MBish) are disjoint, so we need both
+allocators
+// to get as much virtual memory as possible.
