This option controls whether qpdf keeps individual files open
while merging. Prior to version 8.1.0, qpdf always kept all
files open, but this meant that the number of files that could
be merged was limited by the operating system's open file
limit. Version 8.1.0 opened files as they were referenced and
closed them after each read, but this caused a major
performance impact. Version 8.2.0 optimized the performance
but did so in a way that, for local file systems, there was a
small but unavoidable performance hit, but for networked file
systems, the performance impact could be very high. Starting
with version 8.2.1, the default behavior is that files are
kept open if no more than 200 files are specified, but that
the behavior can be explicitly overridden with the
<option>--keep-files-open</option> flag. If you are merging
more than 200 files but less than the operating system's max
open files limit, you may want to use
<option>--keep-files-open=y</option>, especially if working
over a networked file system. If you are using a local file
system where the overhead is low and you might sometimes merge
more than the OS limit's number of files from a script and are
not worried about a few seconds additional processing time,
you may want to specify <option>--keep-files-open=n</option>.
