Comment(by zooko):

 Yeah, if the common operations are just appending an SI to a set, and
 consuming an entire set, then you could easily implement this with each
 set being a file instead of a directory of 0-length files.  Open the file
 and append the (binary, fixed-length) SI to it to add the element the set.
 Read through the whole file, processing each SI, and then rm it to consume
 the set.

 It isn't so easy to *remove* an element from a set, but we don't really
 need to do that for this application, and if we do need to do it it isn't
 that hard -- you just have to scan the whole file to find the SI you want
 to remove.
