Are you still seeing this? I've been trying to reproduce it, but without much success. The number of fds used by the program (as shown in /proc/<pid>/fd) is constant. I can see one apparently extraneous mapping in /proc/<pid>/maps, but only one:
jester:~/programming/aptitude/branches/aptitude-0.3/aptitude> grep pkgcache\\.bin /proc/`pidof aptitude`/maps b3d13000-b44cf000 r--s 00000000 fe:00 1376293 /var/cache/apt/pkgcache.bin b44cf000-b44d0000 rw-s 00c00000 fe:00 1376293 /var/cache/apt/pkgcache.bin b44d0000-b44d1000 rw-s 00c00000 fe:00 1376292 /var/cache/apt/pkgcache.bin (deleted) b44d1000-b44d2000 rw-s 00c00000 fe:00 1376291 /var/cache/apt/pkgcache.bin (deleted) b44d2000-b44d3000 rw-s 00c00000 fe:00 1376263 /var/cache/apt/pkgcache.bin (deleted) I assume that the "deleted" maps are ones that were munmap'd, but that the kernel remembers them for some reason or other. So there is what appears to be one extra mapping, but that's all I see.
