beanstalkd 1.5 100% CPU usage

[Anton]

Hi there,
I am running new beanstalkd 1.5 on my openbsd box in the production
already. It works.

Currently the beanstalkd process is consuming about 100% CPU (1 core)
but working.

I've tried to trace the process and here is the output[1]
I am not a strong C developer... and maybe somebody smarter than me
could help to solve this CPU consuming loop issue or point me to where I
should look? Thanks in advance.

[1] -- ktrace + kdump output:

I remember something like this happening when we reserved a couple hundred thousand jobs and never released them.

Let's use https://github.com/kr/beanstalkd/issues/53 to track this.
