That's a /bin/sh thing. If you pass a list of parameters to  
RemoteShellCommand, it will launch the command directly (that is,  
without going through the shell), so this doesn't work.

Yeah, it will pass a new environment to execve(), which is simpler  
and always works.

Hmm, looks like you're right. Though you could set environmental  
variables when starting the buildslave, if they're always the same.
