SMB module and do_get_file_info

["Philippe Normand" <philippe fluendo com>]

I'm now playing with the Python gnomevfs package. But having issues with
gnomevfs.exists, see the attached code. When looking up for a SMB uri
pointing to a dead machine, the whole python process is locked and i don't
understand why.

So I came up to wonder why the do_get_file_info() function takes so much
time to resolve SMB uris which don't exist.

Tracing my code, it seems to block on the LOCK_SMB() in do_get_file_info()
function, but i really can't figure out why it locks my everything. In the
gnome-python binding, the GIL seems to be well used.

I tried the usual trick (gtk_threads_enter/leave) but it didn't helped at
all. I know this question is heavily Python related, but in the end the
gnome-vfs C package is involved, so i hope somebody would have an idea
about my problem ;-)

Best regards,
Philippe
