The GC is designed to be thread-safe. In a multi-threaded environment a
couple of macros need to be defined to establish mutual exclusion between
the allocator and the collector. These macros call code in a
system-dependent threads module. The latest version (4.13 alpha 3) seems to
have in-built support for threads under linux, irix, solaris and win32.
