[qopen] error on MacOS with multiprocessing / data load

[Jaimes Caballero, Manuel Alejandro]

Hi Dr. Eulenfeld,

That sounds perfect. The line that you provided seems to fix the issue. do
you know if event and stations XML files can be created from .SAC files, I
know all the information is contained in the header but I do not know if
the XML files would have to be created from scratch.

Thanks for your cooperation,

Manuel Jaimes.
