At least from Hudson 1.104 on including 1.106-SNAPSHOT (as of 4 May 2007)

Steps to reproduce:

1. c:\temp\hudson\> java -jar hudson.war
2. Configure system with
master = 0 executors
client1 = at least 1 executor fs root = c:\temp\hudson1
Maven 2.0.5
3. Start client1 via JNLP
4. Add Maven2 build job

The main job will build, the modules will hang with the following build log:
