(usagi-users 02065) Machine crashes when enabling several hundred IPV6ADDR_SECONDARIES addresses on an interface

[Yaniv Kaul <ykaul@xxxxxxxxxxxxxx>]

I've just updated to the latest USAGI snap kit, and the situation has 
improved:
Earlier, it used to crash upon installing ~ 245 interfaces (succeeded 
240, failed 250...). Now, I managed to load 300 successfully, but trying 
more (tried 500 and it crashed, did not bother to find out exactly on 
how many it fails), it seems to crash in the same location:

I'll be happy to supply more debugging information, let me know what's 
needed.
