>From personal experience with PDFL 5.0, using up to 50 concurrent processes
on Windows NT, allow me to make it simple:

No.  No problems at all.

More good news: The PDFL doesn't lock a file when reading from it, so
multiple processes can read from the same PDF at the same time.  Multiple
writes are a problem for obvious reasons.

I used the number "50" above because that's the largest concurrency test
that I can remember running.  In my experience, optimal throughput on my app
was achieved at around 10-15 processes per CPU.  The PDFL spent a lot of
time IO bound.  Anything more than that and the CPU started to spend more
time switching processes than it saved switching away from IO-bound
proecesses.

Your Milage May Vary.
