Bug #10433: make test-all stops at [  401/16011] FTPTest#test_list_read_timeout-exceeded
https://bugs.ruby-lang.org/issues/10433

* Author: Martin Drst
* Status: Open
* Priority: Normal
* Assignee: Nobuyoshi Nakada
* Category: test
* Target version: current: 2.2.0
* ruby -v: ruby 2.2.0dev (2014-10-26 trunk 48146) [x86_64-cygwin]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN
----------------------------------------
When I execute
   make test-all
it stops at
   [  401/16011] FTPTest#test_list_read_timeout-exceeded
for at least an hour. Looking at TaskManager, it doesn't do anything (i.e. it is not in an endless loop).

I have to kill it, one Ctrl-C isn't enough, the second Ctrl-C produces the output below. The terminal then hangs and has to be killed from the outside.

[  401/16011] FTPTest#test_list_read_timeout_exceeded = 3953.02 s
  3) Failure:
FTPTest#test_list_read_timeout_exceeded [/cygdrive/c/Data/ruby-public/test/net/ftp/test_ftp.rb:356]:
[Net::ReadTimeout] exception expected, not.
Class: <Errno::EPIPE>
Message: <"Broken pipe">
