No, if a child crashes, there is only an entry in the error log about 
the crash but no details about the requests in progress.  
Mod_log_forensics would be an easier way to get those than 
mod_whatkilledus (which requires recompiling with --enable-exception-
hook IIRC).

Sergio, it would be nice if you could file an enhancement request in 
bugzilla, so that this idea is not lost.
