Bug #108670 for TAP-Formatter-TeamCity: Module raises exception when prove uses multiple jobs

When I use -j2 as a parameter to prove to run tests in parallel, an exception is raised. This means the formatter can only be used to run tests in serial. Attached is a test. Here is the output: pete@perl-builder:~/scratch/tc_tap_test$ prove -lvr --formatter TAP::Formatter::TeamCity t/##teamcity[testSuiteStarted name='t/1.t'] ##teamcity[testStarted captureStandardOutput='true' name='No test name given'] ##teamcity[testFinished name='No test name given'] ##teamcity[testSuiteFinished name='t/1.t'] ##teamcity[testSuiteStarted name='t/2.t'] ##teamcity[testFinished name='No test name given'] ##teamcity[testStarted captureStandardOutput='true' name='No test name given'] ##teamcity[testFinished name='No test name given'] ##teamcity[testSuiteFinished name='t/2.t'] All tests successful.
