I owe you a beer. You're absolutely right .. the code that I'm calling does do some futzing around with pipes to call Ghostscript .. it's not my code, I'm just calling it, but I should have guessed (or even checked) that there were pipes involved.

And that's not on .. Apache has taken control of the input and output pipes in the main process .. meaning if I want to do something *like* that, I have to start a sub-process and talk to it directly. So Apache was burping when it saw the code I was calling start to rearrange the plumbing, I guess.

Well, it's going to get tricky later when I want to start a sub-process if one isn't yet running for a document, use it for a page image, and then leave it in place for subsequent requests for the same document.
