I experimented with pstops, and it does seem to produce a non-rasterized
PS file, which can then be converted back to PDF without transparency,
thus sidestepping this issue. I'll use that as a workaround for now.

I discovered that converting the pdf to ps and back again significantly
reduces the file size. So it's kinda my poor-man's way of compressing
pdfs. Of course, this only works if your pdf doesn't contain any
features incompatible with ps, which in my case is true. And now that I
know that pdftops does a proper job with the conversion even when there
is transparency, it's a sufficiently-acceptable solution to this issue.

I wonder if it has to do with the amount of available RAM, as my PC is
10+ years old, so on a more modern machine the difference would be
unnoticeable.
