        posix_mq 0.5.1
        
        Fix POSIX_MQ#notify(&block) usage, this regression was
        introduced in 0.4.0 and our tests for it were broken, as well.

        fix POSIX_MQ#notify(&block) aka SIGEV_THREAD
        
        tests for them were stupidly broken and never executed :x

        posix_mq 0.5.0
        
        Uncommonly raised exceptions due to programmer error are now
        raised more safely with respect to the MRI garbage collector.
        
        The "posix-mq.rb" executable has been renamed to "posix-mq-rb"
        to respect RPS and is also hopefully easier to type/read when
        used in scripts.  I'm preserving the "rb" in the name since I
        hope to have a more portable, C-only version someday.
        
        Minor cleanups and documentation now uses RDoc 2.5.x

        doc: updates for RDoc 2.5.x
    
    commit 7b1b8a1cbbedc2764d4a8ab0d992f9f2ef73d9b7
    Author: Eric Wong <normalperson@yhbt.net>
    Date:   Tue May 4 19:31:47 2010 -0700
    
        rename `posix-mq.rb' executable to `posix-mq-rb'
        
        ".rb" in the executable name is discouraged by the
        {Ruby packaging standard}[http://github.com/chneukirchen/rps]
        and probably confusing.
        
        If I ever get around to it, a non-Ruby version of this
        executable is planned, and that will be called "posix-mq"

        GC safety fixes
        
        Avoid the RSTRING_PTR(rb_inspect(val)) construct, as it may not
        preserve the value of rb_inspect() on the stack.
    
    commit a9a365326ea0f7a37852d25adfb03049c0b24c22

        cleaner lookup "Signal" of constant
        
        Instead of blindly defining a module, this is more flexible in
        case Signal in Ruby itself becomes something other than a
        module.
