Only one process is permitted to be running the compiler at a time. It
used to be that if you tried to run the compiler in two processes at
once, you got strange and mysterious errors; now the second process
waits for the first one to finish. It waits in process state "Lock",
which you may see in the who-line if this happens to you.
Actually the process state is "Compiler". If you get "Lock", something
else is locked. This problem may be totally circumvented shortly.
