fix race condition between doctest creation and running

[sagetrac-mabshoff]

With high -tp numbers (i.e. 16) on sage.math one will see similar issues to the one below:

sage -t -long devel/sage/sage/libs/symmetrica/symmetrica.pyx
  File "/scratch/mabshoff/release-cycle/sage-3.2.alpha0/tmp/.doctest_symmetrica.py", line 29
    >>> test_integer(Integer(1))###line 539:_sage_    >>> test_integer(1)
    ^
IndentationError: unexpected indent

This is likely a race condition between creating the file and the actual running of the doctest. The issue is not specific to -tp.

A potential solution might be to create all .doctest_$FOO files and then start running them. This might also fix the problem with

sage -t -long devel/sage/sage/symbolic/constants.pyx
 [0.1 s]

in Sage 3.2.1+ which is caused by no doctests being executed since (a) either there are no doctests in that file or (b) we are running optional doctests only.

Cheers,

Michael

don't apply anything!

I think this is an old ticket which can be closed and has been fixed in the mean time. At least during the parralel builds I did (and I did quite a few this sage days already) I never saw this message.
