memory corruption when user-interrupts and tcp

[kristianlm]

It seems user interrupts from csi, when reading from tcp ports causes memory corruption. As shown in this paste: ​http://paste.call-cc.org/paste?id=ae7e3a52e4a71cf9c1c6697234d168a343022309

~$ csi -n

I am reproducing this on Linux 3.18.6.

There's a patch for fixing the scheduler, which needs some more attention

I can no longer reproduce this bug. It looks like this was fixed at the ICC with 4e32262036806b2fc51964e518135fcd3de3a79b
