On the 64bit Windows installations two eerily similar heap sections appear
much higher in the process image:

80000000-80070000 rw-p 00000000 0000:0000 0                   [heap]
80070000-98000000 ===p 00070000 0000:0000 0                   [heap]

Hm....  why would something like that move from 2GB down to 0.5GB?

Regards,
Achim.
