Hello,
Afaik it will happen:
First it will try to kill you 'softly', and it'll get more agressive
after that.
So, I think if you exit fast enough after getting a signal, there will
be no problem. (This will be more than at least one second).
So if you start hurrying and get your data written, there will no problem.
(I advise you to die yourself, that will safe the mpm from spending
'much' time on you, and you won't get surprised by some SIGKILL on a
'random' moment after it.)
Note: Core-dumping-signals will (sometimes ?) be passed right to all
childs, when the master got hit by it
Please correct me if i'm wrong.

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.
