Re: ppp_async kfree patch

This patch has fixed the kernel hangs I had been having on a system
using three instances of pppd a USB HSDPA modem.

In the situations where the hang would normally occur, what I now see is
disconnection and reconnection of the USB device, apparently triggered
by electrical noise or RF interference.

I presume that what was happening before this patch was that the
disconnection of the USB device caused a deadlock, associated with this
area of ppp_async.
