The two libc functions are getpid() and sleep().

Of the 5 pages, 3 are data pages from libc.  I have no idea why.  What would
write to them?

At least 1 of the other 2 pages is undoubtedly a bss page from libc, on account
of an uninitialized variable 'ringring' declared in sleep.c.  I'm unable to
track down getpid() in the libc source, so the other page, I don't know.

As for the GOT, I can count on one hand the symbols that are being linked.
