cpu profile can not work after invoke fork()

[GoogleCodeExporter]

What steps will reproduce the problem?
1.use fork() in your codes
2.link and run
3.

What is the expected output? What do you see instead?
can get child's cpu profile data when process terminated , but nothing.

What version of the product are you using? On what operating system?
gperftools-2.0 linux 2.6

Please provide any additional information below.
1.setitimer can not be inherited after fork()
2.CpuProfiler has one static instance, CpuProfiler::Start() invoked in it's 
constructor, and CpuProfiler::Start() only do 'setittimer' one time even 
several invoke. 
3.So, there is no signal generator after fork even you invoke ProfilerStart()

Workaround is to do ProfilerRegisterThread after ProfilerStart in child
