Yes on linux. The heapsort in the library uses nearly the same code as the
one provided with tin (the libs version may have an overflow problem with
large arrays as it uses int instead of size_t for several vars; I guess this
will be fixed in the next release) and I doubt that someone will optimize
that code in the (near) future. So (currently) the only benefit would be
a smaller (but less portable) binarie. If there will be some optimization
later on using the libs version may be a win...

I'm fine with the current solution - I just wanted to mention the existence
of the library. <http://libbsd.freedesktop.org/wiki/>
