Here's my result:

Mmm, this may not be informative ;(

BTW, I found that tDiary (http://www.tdiary.org) doesn't work with `no
native pthread'
version of ruby.  I tested with both version 2.0.2 and 2.1.4.
Contrary to the bsfilter,
`native pthread' version of ruby works well for both versions.

I'll file this as another PR later.
