This is strange I cannot reproduce this on my ubuntu 11.10 box with python 2.7:
$ python sklearn_error.py
/home/ogrisel/coding/scikit-learn/sklearn/cross_val.py:2: UserWarning:
sklearn.cross_val namespace is deprecated in version 0.9 and will be
removed in version 0.11. Please use sklearn.cross_validation instead.
warnings.warn('sklearn.cross_val namespace is deprecated in version 0.9'
[Parallel(n_jobs=4)]: Done 1 out of 30 | elapsed: 0.0s remaining: 0.5s
[Parallel(n_jobs=4)]: Done 50 out of 50 | elapsed: 0.2s finished
[Parallel(n_jobs=4)]: Done 1 out of 33 | elapsed: 0.1s remaining: 1.9s
[Parallel(n_jobs=4)]: Done 200 out of 200 | elapsed: 1.0s finished
Maybe this is caused by a fork / GIL deadlock issue? I don't think we
use threads in scikit-learn nor in libsvm though,
