Bug#401595: performance regression in rxvt-unicode-ml with libx11-6 2:1.1-2

[Bryan Donlan <bdonlan@gmail.com>]

Package: libx11-6
Version: 2:1.1-2
Severity: normal
Tags: experimental

When I upgrade to libx11-6 and attempt to use rxvt-unicode-ml, urxvt
seems to spin, causing high CPU usage and slow response time. stracing
the process shows a lot of:
read(5, 0x8184438, 4096)                = -1 EAGAIN (Resource temporarily unavailable)

Downgrading to libx11-6 in sid fixes the problem.
