Description
If there is problem with SCM polling hanging (as in JENKINS-4461) and you try to manually start a job, Hudson will duly schedule it on an executor and then seem to run it. When you look at the console, it says e.g.
--%<--
Console Output
--------------
Started by user jglick
Building remotely on someslave
--%<--
and then nothing else happens - indefinitely. This is not friendly.
If the build has to wait to acquire a workspace lock, it should say so... and give you information about how to kill any outstanding polling process (JENKINS-4479).

I think the problem is something else. When I run a build using Mercurial on master, I see:

When I run a comparable build on a slave, I see only

No wonder it looks like nothing is happening - various time-consuming commands are being run but no indication of this is printed.
LocalLauncher.launch immediately calls maskedPrintCommandLine. But RemoteLauncher.launch does not appear to do anything comparable. RemoteLaunchCallable.call does call LocalLauncher.launch, but it constructs it with TaskListener.NULL!
