Okay, I've been running the same instance of ruby-wmii for about 50 hours
now and it feels quite stable. There have been no visible or
feelable failures neither in wmiirc nor in wmii. However, it looks to
me like there's a memory leak somewhere:

,----
| athene:~# ps aux
| USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
| [...]
| olli 7531 2.4 23.2 162384 150524 ? Sl Sep30 74:06 ruby /home/olli/.wmii-3/wmiirc
| [...]
`----

A freshly started wmiirc uses about 2.8% of the memory:

| olli 13956 6.1 2.8 28624 18608 ? Ssl 14:34 0:09 ruby /home/olli/.wmii-3/wmiirc
`----

I put the log file on my website, as it is quite big and I didn't want
to attach it to this list:
