> This is mostly good. The only problems are with the parallel version:
if I run with more than one process, I get a message like
> {{{
> sage: X.is_cohen_macaulay(2)
> Killing any remaining workers...
> False
> }}}
> If I run it with one process, I get
> {{{
> sage: X.is_cohen_macaulay(1)
> Killing any remaining workers...
> Exception OSError: (10, 'No child processes') in <generator object
__call__ at 0x10ca39a00> ignored
> False
> }}}
> We should be able to catch the error. Can we also suppress the message
"Killing any remaining workers..."?
I tried to catch it, but it it already caught somewhere inside the
decorator, so I don't know how to suppress the output, do you?
Feel free to update the patch if you see a way to do it!
