  http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=rev&revision=27999

  Log:
    Added --disable-ucontext, to be used with --enable-pthreads, to improve performance when built with pthread support by eliminating the oodles of sigprocmask calls that otherwise occur.

+	* configure.in: Bug #2553 [ruby-core:27380]; Add a --disable-ucontext option, for use with --enable-pthreads, to avoid performance loss from --enable-pthreads and the oodles of sigprocmask calls that normally brings.

-	* lib/cgi.rb: Backport #229 [ruby-core:17634]; CGI::Cookie objects can get out of sync when CGI::Cookie#value= is used to assign a new value. Also, if a nil value ends up in the array of values for the cookie, CGI::Cookie#to_s would blow up on a gsub error when it tried to CGI::escape the nil value. This is fixed so that nils are treated as empty strings.
