That depends on what you mean by "inefficient". Assuming you aren't
making massive changes to files when you check them out, it is very
efficient for disk space, at the expense of checkout and checkin 
time.

One problem I have seen is that the SunOS 4.1 version we used had
a bug that rendered a file impossible to check back in if it was
checked out from an "su"ed session. I hope that has been fixed.
