Bug #6249: Process.exec doesn't restore the environment if it fails
https://bugs.ruby-lang.org/issues/6249

Author: john_firebaugh (John Firebaugh)

ruby -v: ruby 1.9.3p125 (2012-02-16 revision 34643) [x86_64-darwin11.3.0]


>> ENV["foo"]
=> nil
>> Process.exec({"foo" => "bar"}, "nonexistent")
Errno::ENOENT: No such file or directory - nonexistent
	from (irb):2:in `exec'
	from (irb):2
	from /Users/john/.rvm/rubies/ruby-1.9.3-p125/bin/irb:16:in `<main>'
>> ENV["foo"]
=> "bar"

I expected that Process.exec would either use execle or execve, or (if it implements environment modification itself), to manually restore the existing environment upon failure.
