   hi,
     I dont't know if it is a memory leak or a feature of the fuse cache :
     # fuse-2.8.1/example/fusexmp /mnt/fusexmp

      #  for  i  in  `seq  1  500`;  do for j in `seq 1 500`; do mkdir -p
   /mnt/fusexmp/$i/$j; done; done
      At the beginning  :
     # ps auxww | grep fusexmp | grep -v grep
   root      23183   0.0   0.1   18492    572  ?        Ssl  08:42   0:00
   /root/fuse-2.8.1/example/.libs/lt-fusexmp /mnt/fusexmp
      At the end :
      # ps auxww | grep fusexmp | grep -v grep
   root      24683   4.5   3.2   43420  16952  ?        Ssl  07:57   1:47
   /root/fuse-2.8.1/example/.libs/lt-fusexmp /mnt/fusexmp
      # uname -a
   Linux  debian  2.6.22.18 #9 PREEMPT Fri Sep 25 22:31:59 CEST 2009 i686

This looks perfectly normal.  Fuse will eat some memory for caches,
but the increase in memory usage shouldn't continue indefinitely.

Thanks,
