Besides this, Cyril some time ago suggested to define TST_NO_DEFAULT_MAIN in
nfs05_make_tree.c [1], which is also helper like netstress.c.

Looking what this would be required for netstress.c: implement function it's own
tst_brk(), which would call cleanup() function before calling library's
tst_brk(), parsing getopt parameters, calling setup() in main() etc.
The only thing which works is tst_res() and tst_brk() printing.
I'm not sure if this is worth just to avoid problematic timeout.

Kind regards,
Petr
