The current version of Hoard, libhoard-2.0.6, is a link-time or
load-time replacement. But the new version, libhoard-2.1.0pre2, includes
DLL patching for Windows. Whenever a new DLL is loaded, the new version
patches in calls to Hoard allocation functions, replacing the original
calls. Things are much easier in the UNIX world, where setting the
LD_PRELOAD environment variable does the job.
