Comment:

 After increasing SAGE_TIMEOUT, the following tests passed:
 * sage/plot/graphics.py
 * sage/plot/plot3d/implicit_plot3d.py
 * sage/plot/plot3d/plot3d.py
 * sage/schemes/elliptic_curves/heegner.py

 The following still fail:
 * sage/plot/plot.py problems with GSL like sage/gsl/ode.pyx (GSL handler
 blabla)
 * sage/schemes/elliptic_curves/ell_rational_field.py fork erros it seems
 when starting external programs
 * sage/tests/cmdline.py seemingly fork errors (calling os.fork() might not
 be a great idea)

 And there is the one I omitted before:
 * sagenb/misc/misc.py # Exception from doctest framework
 The exception bit seems to be from an error I had with previous release as
 well about an alarm set to 1 second and is random.
 I guess Cygwin is just to slow for such a timeout.
 After a few tries I indeed get a bunch only one real error on the test
 with 'print "ignore this' because of a (Python) RuntimeError about "no
 available port" from the find_next_available_port function.
