Description of problem:
When a parent process starts up several child processes that share the same 
standard output stream, the output to cout is mangled in the output file.

Some of the child tasks are multithreaded, and the calls to cout are contained 
with in a flockfile( stdout ) and funlockfile( stout ) calls.  Output from 
multiple threads in the same task is correct; it is just output from the 
several child processes that are mangled.

I have created a test program that exposes the problem.  Ten child process are 
forked that each output the same line of text repeatedly.  All processes are 
single threaded in the test case.  The test case output is correct on g++ 2.96, 
or 2.95.

The output is not mangled on gcc 3 if the cout output operators are replaced 
with printf calls.
