Re: [Xen-devel] [PATCH 5 of 9] libxl: only use interactive PyGrub mode when a console is attached

Well Ian Campbell proposed to use a timeout in select and drop data
when the timeout is hit, that what I've implemented in

libxl: drop bootloader output if xenconsole file descriptor is not
available for writing

The patch is quite simple and solves the problem, I don't think it
interferes with normal boot process, since a 1s timeout is quite high
for data to be delivered from xenconsoled_fd to the user if the
console is attached. The other option would be to modify xenconsole
daemon, but I think that's far too complicated for a problem that can
be solved easily.
