[gt-users] gt python with (multi)processing

[Brent Pedersen]

hi, multiprocessing is in the python stdlib as of 2.6:
http://docs.python.org/dev/library/multiprocessing.html

i am unable to use it to parallelize stuff when working with gt python
because i see segfaults when using multiprocessing
with FeatureIndexMemory.
the script below segfaults on my machine. i add the gff3 file twice as
sometimes the segfault does not occur for that file (which
is included with genome tools).

so, i guess this is a bug report, unless it's known that i shouldn't
do such things.

#import multiprocessing as processing
import processing
import gt
p = processing.Pool(4)

f = gt.FeatureIndexMemory()
f.add_gff3file('./testdata/encode_known_genes_Mar07.gff3')
f.add_gff3file('./testdata/encode_known_genes_Mar07.gff3')
