Fun with file descriptorsFun with file descriptorsPosted Jun 14, 2007 7:51 UTC (Thu) by slamb (guest, #1070)In reply to: Fun with file descriptors by felixfix Parent article: Fun with file descriptors I'm not sure about a "no-no", but exec*() is generally preceded by fork(), and I'm told a fork() in large threaded programs can be extremely slow. Apache uses an external forking server for this reason. Other caveats include that in the fork()ed child process, it is as if all other threads suddenly died, and they still hold whatever mutexes they were holding. So any resources the child requires (before calling exec*()) need a pthread_atfork(3) handler or similar.
