#11344: KDL while running PHP testsuite: "failed to acquire spinlock %p for a
long
time"

A recipe for php 5.6.2 is available at haikuports. Building it and running
the testsuite results in a repeatable KDL. the error happens in
{{{_php_stream_fopen_from_pipe}}} which calls _user_unmap_memory and ens
up in a reschedule.
I tried to debug this as requested in #11032, but results are strange.
{{{running}}} shows that the 3 other cores in my CPU are running idle
threads. This looks correct, the machine freezes for a short time before
it panics, but it is unexpected.
Trying to analyze the spinlock results in {{{locked from 0x0000000}}}. So
it looks something went wrong with the spinlock.
