I have a hunch it's because of how the OS's are reporting shared memory
usage.  IE, the 1 MB increase under windows may not be altogether
truthful, and neither is the reported 40 MB on linux.  Memory usage is
tricky to judge on any modern OS, as shared libraries do increase the
apparent memory use by an application, but the libraries are shared with
other applications and OS components.
