There's not much going on in unicorn.git nowadays, everything's
stabilized nicely over the past few years.
This release would mainly be for for Graham's EPERM fix/workaround for
stale pid files and some documentation fixes improvements.
Shortlog below:
Eric Wong (4):
examples/nginx.conf: remove redundant word
examples/nginx.conf: use $scheme instead of hard-coded "https"
KNOWN_ISSUES: document signal conflicts in libs/apps
log EPERM errors from invalid pid files
Graham Bleach (1):
Start the server if another user has a PID matching our stale pidfile.
$ git clone git://bogomips.org/unicorn.git
I'm also going on vacation soon, so I'll have almost no Internet access
for a few weeks. Help each other out when I'm away, thanks :)

Eric,
I have been unable to narrow down the cause of the conflict so far. The list of Ruby gems (and gem versions) on the affected deployment are identical to the ones on another deployment where Unicorn is upgrading just fine (with preloaded app). Grep'ing for USR2 in the gem installations did not reveal anything, unfortunately. Since then, I haven't been able to spend further time investigating. Not sure where else to look, really, but I'm open to further suggestions.
-Jeff

Btw, did you ever figure out what was causing the conflict?
