The current user might not have the right to write in the install directory. What about multiple users on the same computer?

If you write one line at a time you will get a mixture of different sessions that will not be very helpful. You must also make sure that the instances are writing one after another. And what about command-line usage? We use Jmol.jar for example for producing automatically about 300000 images for all PDB structure by a complex script with about hundred lines of code. I wouldn't want that to be slowed down by writing into a history file for each line (and coordinating to do this from 30 processes in parallel).
