You will need to recompile the procps RPM after upping NR_TASKS, but
yes, linux/include/tasks.h is the only place it needs to be changed.

Note, however, that (/proc based) top(1) is extremely CPU intensive
when there are more than 2000 threads running.  I'm guessing it is at
least O(n*n), probably much worse.  (Based only on empirical
evidence.)  In short, unless you have a recent, high-end CPU, don't
even *think* of running it when there are 2000+ threads.
