Do the worker and prefork MPMs forcefully kill child processes?

[Hongli Lai]

Hi, this is a question about Apache module development. I'm not sure 
whether I'm writing to the right mailing list, but this topic doesn't 
seem belong to the user mailing list. Please forgive me if I should have 
sent this email to a different mailing list.

I'm planning on using shared memory in my Apache module. This shared 
memory contains data structures, and will be read from and written to by 
all the Apache processes and threads. Needless to say, the data 
structures must be kept in a consistent state.

So I'm wondering whether the prefork and worker MPM will ever forcefully 
child processes. If that happens then I won't be able to keep my data 
structures in a consistent state.
