Hmm.  This seems like a bug in the sorting code.  It shouldn't
allocate all that memory in advance.

I didn't realize at the time I wrote the sort code that there
would be a situation where we had a large number of sorters, so I
didn't think of allocating incrementally.

I doubt that it will be too difficult to fix this.  I filed it as
bug #35887.
