This hashing function will have lots of conflicts when used in
hash-table. It's quite easy to guess how it's done in native dll:

for(i=0; i<len; i++)
     hash = (hash<<4) + hash + name[i];
hash %= 1201;

It would be nice to add some tests for strings containing '\0'
characters and for other VARIANT types. I don't know how scrrun stores
data internally, if it's using a hash-table, the function may change
after adding some elements.
