When running under the debugger, the max-open-files limit is increased
for some reason. You can increase the limit yourself with the BSD call
"setrlimit" and RLIMIT_NOFILE.
AFAICS there is no penalty to your app for increasing it to the maximum
value. I think it is just there so that runaway processes die sooner.
For more info, /man setrlimit

I am working on a Foundation tool which calls fopen() from a class

Sounds like your code depends in some way on the current working
directory. Also, why are you using fopen() instead of
-dataWithContentsOfURL: or -stringWithContentsOfURL:?
Thanks for your response.
The path to fopen is absolute, and I am opening it for writing. I
don't see how this can be affected by the working directory.
I am using fprintf instead of accumulating a string and writing it all
at once because hundreds of writers are distributed throughout the
program tree, and each is asked to write thousands of times. It seemed
that having them write through a shared file stream would be quicker
than mutating a string a hundreds of thousands of times.
