	Hello
Sometimes when I reload unicorn I receive different errors, usually these are system errors, starting with Errno.
Last time it was:

Errno::EINTR: Interrupted system call - identify -quiet -ping -format "%w %h\\n" "/tmp/mini_magick20140226-3105-gexmt1"

It's pretty clear that image processing process was interrupted, but why it happened? As I understand unicorn should wait until it's children will complete current request.

Thanks.

This appears to be a bug in (older) Ruby itself:
 https://bugs.ruby-lang.org/issues/8770

The latest Ruby releeases (2.1.1, 2.0.0-p451, 1.9.3-p545) should have
this fixed.  Please let Ruby developers know if you still hit this error
with the latest versions.  Thanks.
