Bug#688314: Testcase is racy

[Sjoerd Simons]

Package: libipc-run-perl
Version: 0.92-1
Severity: normal

Sometimes when building libipc-run-perl the testsuite fails as follows:

t/pty.t .. 1/32 
#   Failed test at t/pty.t line 170.
#          got: 'hello'
#     expected: '(?^:^hello\r?\n(?!\n)$)'
# Looks like you failed 1 test of 32.
t/pty.t .. Dubious, test returned 1 (wstat 256, 0x100)
Failed 1/32 subtests 

It looks like there is a race condition somewhere and can be reproduced using:
  while [  $? -eq 0 ] ; do
      PERL_DL_NONLAZY=1 /usr/bin/perl "-MExtUtils::Command::MM" "-e" "test_harness(0, 'blib/lib', 'blib/arch')" t/pty.t ;
   done

Sometimes the test fails after just running it a few times, sometimes it takes
30 seconds. Which is most likely why it's not usually a problem to run the test
on the debian build machines.
