Actually, we do have a good reproducer.

I inserted calls to force a context switch each time a radix tree node
is allocated, and I got the assertion right away. I then applied Justus'
patches along with the error injection code and could run the system
fine. I then proceeded to build some packages and run a benchmark
tool (sysbench) to stress the file system, which is the biggest ipc
space users, and had no trouble.
