Support forked processes to log to different log files

What steps will reproduce the problem?
1. Write C++ program that logs something using glog library
2. Fork into another process and log from there too
3. Note how both logs go into the same on-disk file

What is the expected output? What do you see instead?

I'd prefer to see a way to configure glog such that forked processes write to 
their own separate log file.

What version of the product are you using? On what operating system?

glog 0.3.0. Ubuntu 10.10.

Please provide any additional information below.
