Is your system 32-bit or 64-bit?  It makes a difference in determining
whether there is a bug in the OS sleep primitives (for example, we know
that 64-bit Linux has a bug where nanosleep with an extremely large
value will cause the kernel to overflow and sleep for the wrong amount
of time, but coreutils has workarounds in place for that).

Also, consider upgrading; the latest stable coreutils release is 8.6,
and there have been some gnulib fixes in the meantime to improve the
robustness of the sleep workarounds in use by coreutils.
