Hello,

As originally mentioned in [ruby-core:55416], a particular test on ruby_2_0_0 branch and trunk is leaving temporary files behind and causing the CI worker to have no free space.

The failing test:

http://ci.rubyinstaller.org/job/ruby-2_0_0-x64-test-all/87/console
http://ci.rubyinstaller.org/job/ruby-trunk-x64-test-all/1371/console

2. Error:
   TestIO#test_write_32bit_boundary:
   Timeout::Error: Timeout::Error
   C:/Users/Worker/Jenkins/workspace/ruby-trunk-x64-build/test/ruby/envutil.rb:78:in invoke_ruby' C:/Users/Worker/Jenkins/workspace/ruby-trunk-x64-build/test/ruby/envutil.rb:298:in assert_separately'
   C:/Users/Worker/Jenkins/workspace/ruby-trunk-x64-build/test/ruby/test_io.rb:2693:in block in test_write_32bit_boundary' C:/Users/Worker/Jenkins/workspace/ruby-trunk-x64-build/test/ruby/test_io.rb:1247:in make_tempfile'
   C:/Users/Worker/Jenkins/workspace/ruby-trunk-x64-build/test/ruby/test_io.rb:2692:in `test_write_32bit_boundary'

And ruby_2_0_0:

1. Error:
   test_write_32bit_boundary(TestIO):
   Timeout::Error: Timeout::Error
   C:/Users/Worker/Jenkins/workspace/ruby-2_0_0-x64-build/test/ruby/envutil.rb:77:in invoke_ruby' C:/Users/Worker/Jenkins/workspace/ruby-2_0_0-x64-build/test/ruby/envutil.rb:266:in assert_separately'
   C:/Users/Worker/Jenkins/workspace/ruby-2_0_0-x64-build/test/ruby/test_io.rb:2674:in block in test_write_32bit_boundary' C:/Users/Worker/Jenkins/workspace/ruby-2_0_0-x64-build/test/ruby/test_io.rb:1246:in make_tempfile'
   C:/Users/Worker/Jenkins/workspace/ruby-2_0_0-x64-build/test/ruby/test_io.rb:2673:in `test_write_32bit_boundary'

The test (({test_write_32bit_boundary})) is not properly cleaning up the temporary file it creates.

This was not a problem before and just recently started to happen. It is worth to mention no change in the worker setup has been made except normal Windows security upgrades.

Ideas?

test_write_32bit_boundary still fails on CI.

TestIO#test_write_32bit_boundary = 137.43 s = E

http://ci.rubyinstaller.org/job/ruby-trunk-x86-test-all/1566/console

I tried the test on my local Win7 and took about 50s to complete with changing timeout to 60s. And the test creates a 4.2GB temp file.
Since it takes very long time and fails on CI, is it better to skip the test on mingw?
