This is a guard that tracks down UIKit access on threads other than main. This snippet is taken from the commercial iOS PDF framework http://pspdfkit.com, but relicensed under MIT. Works because a lot of calls internally call setNeedsDisplay or setNeedsLayout. Won't catch everything, but it's very lightweight and usually does the job.You might n…

Performace patch for ruby-1.9.3-p327

Changes:

  • this version includes backport of Greg Price's patch for speedup startup http://bugs.ruby-lang.org/issues/7158 .

    ruby-core prefers his way to do thing, so that I abandon cached-lp and sorted-lf patches of mine.

  • this version integrates 'array as queue' patch, which improves performance when push/shift pattern is heavily used on Array.

    This patch is accepted into trunk for Ruby 2.0 and last possible bug is found by Yui Naruse. It is used in production* for a couple of months without issues even with this bug.
