On "large" machines, Tiger ergonomics causes javac to run under the server
compiler instead of the client compiler, resulting in a severe performance
degradation. The javac launcher should turn off ergonomics by specifying
-J-client on the javac default command line.

Measured a performance degradation of 40% elapsed time for compiling
35000 source lines. CPU time degradation of 145% (due to the use of multiple
CPUs).
