I think this behaviour would depend on the load on the system. If your
server is not being used as a multi user system and is lightly loaded, you
would probably see this behaviour. On a heavily loaded system, anything is
possible! Then again, if this is Linux, I don't know how similar to the
commercial flavours of Unix it is in this regard.
