That doesn't seem right. GS> means that Ghostscript is waiting for
input. GS<1> means that Ghostscript is waiting for input and there is
one item left on its stack (which is where PostScript passes data
around). I don't think that this should regularly be the case.

preview-image-type to 'dvipng ]]]
Well, I never pretended to understand the first thing about how gs operates, I
am just making observations...
Here is the output of some debugging messages : printing the gs prompt and a
directory listing for the preview dir.
Type ‘C-c C-l’ to display results of compilation.

This was with preview-gs-outstanding-limit = 2. With 5 and preview-image-type
set to 'png I get the same general behaviour :
Type ‘C-c C-l’ to display results of compilation.

So notwithstanding what GS thinks its prompts mean, it looks from where I am
that I can take GS<1> for "image is ready".
Of course if you have a better solution / understanding of what is happening I
am eager to learn. In any case the bug I reported is real and this looks like
a solution.
All the best,
