The restart patch has been updated: the variable initialization was lost when
separting the patches.

I also thought about this and it looks like a good idea for me too.

We could return with error in this case (for me this almost the same as if we
don't create file at all). But if we check pidfile_write() status we should
resign the pidfile_write() feature that allows to pass NULL pidfh and check if
pidfile option is used. Something like in this patch:

Not sure I should commit this though.
