Xen devel - Aug 2005 - [PATCH] Fix SEGVs in xenconsoled

Under the right circumstances, xenconsoled will corrupt its internal 
list of domains causing a SEGV.  This is usually characterized by a 
rapid number of creations/destructions.  The attached patch fixes this.

Regards,

Anthony Liguori

I''m seeing frequent short pauses and even ocassional hangs from console
clients. Any chance this will fix that?

Thanks,
Ian

I think this should fix the hangs from clients.  The code base is small 
so once I can reproduce a problem I can solve it pretty quickly.

The short pauses are part of the throttling to combat corruption.  We 
could get rid of the throttling and just deal with the corruption for 
now until we get the new console drivers.
