Subject: Severe issue with two Threads and load and eval

I have trouble with executing load and eval in two concurrent Ruby Threads.
The code from 'eval' is appended to the file loaded and a Syntax error
appears in the thread executing 'load'.
(Environment is Ruby 1.6.6./mswin32/Windows2K)

It's easy to reproduce:
Skript1:
#Beginning of Skript 1
Thread.new {
        while true
                eval "puts 'Hallo'"
                Thread.pass
        end
}

1000.times do  |i|
        a = i
        load "e.rb"
end
#End of Skript 1
The file loaded named "e.rb" is empty - but you may fill it with something
short.

The ouput is the following:
------------------------------------------
ruby 1.6.6 (2001-12-13) [i586-mswin32]
Hallo
Hallo
:11:in `load': ./e.rb: syntax error (SyntaxError)
puts 'Hallo'
            ^
 from :11
 from :9:in `times'
 from :9

Tool completed with exit code 1

------------------------------------------

How can I work around this? I have absolutely no idea what is going wrong,
as I do not really understand the compiler!
