I already sent me my thank you privately. And now I can ease Corinna's life, 
too, because I must excuse myself for suspecting a problem in mmap(). I was 
wrong, because mmap() seems to work perfectly fine.

The problem I have with loosing memory on Win98SE happens when I repeatedly 
fopen/fread/fclose the device /dev/urandom. Everytime I do this I loose a 
good chunk of memory, which only by accident was about the same size as my 
mmap()ed region and thus led me to search in the wrong place.

For now I can deal with it by opening /dev/urandom only once in the parent and 
using the duplicated filehandle in the child processes (I hope this will fix 
it - not yet done), but someone should inspect the code there to see where 
the memory leak is.
