| Subject: | [TEST] Test case for "unexpected _child(lose) for a detached session from _start" |
In november 2009 I reported on the POE mailing list a problem about an
unexpected _child(lose) event for a detached session from _start
http://www.nntp.perl.org/group/perl.poe/2009/11/msg4684.html
This problem has since been fixed.
However I've not found any test in the test suite that tests this
particular case. t/90_regression/neyuki_detach.t does not check it.
So here is one test to add to the POE test suite to avoid regressions.
