We use POSIX functions like sleep() without thinking about it, and simply forget looking for an EAL variant of the function first.

it's easy to make this mistake if by including dpdk application headers
we indirectly introduce platform specific headers into the applications
namespace.

if this wasn't happening the application would be forced to confront the
issue by directly including unistd.h itself directly making it more
obvious that they were writing inherently non-portable code.

i think this is being fixed but it is a work in progress but it
highlights the reason why there needs to be scrutiny around what goes
into the eal and other library headers.
