Summary0000282: Solve problem with pdf inclusion and maximum number of open files
DescriptionCurrently luatex when including pdfs works in two phases:
- first (\pdfximage) the pdf is opened and some information (size
  etc.) is extracted
- later when writing the page the pdf is read and copied to the output
Since the pdf is kept open during the whole process, the number of
pdfs that can be included this way is limited by the number of files a
program can open at the same time (typically 1024). The work-around
for this is to make \pdfximage \immediate: luatex then writes out the
output file immediately and closes the pdf.

If we want to keep the two-phase approach, I propose a different way:
Get some information about the pdf that uniquely identify it
(timestamp, size, id, md5?) from the pdf in the first phase and close
it. Later open it again when needed and check the information from the
first phase - and raise an error when the file has vanished or changed.
TagsNo tags attached.

Just storing the modification time and size should be enough, I think.
