ssh -p <JENKINS_SSH_PORT> <USER>@<JENKINS_HOST> build Test -s -v

I'm using jenkins version 1.476

fails on a busy build host (in this case single CPU) because the log file creation does not happen before jenkins (the build cmd) starts reading it.
Basically the future returns, the code starts reading the log file, but the actual task has not yet created the log file. This occurs reliably on a busy (hence slow log file creation) single CPU build machine. The exception is:

java.io.FileNotFoundException: /home/jenkins/jobs/Test/builds/2012-08-13_08-44-53/log (No such file or directory)
