Subj : fork & exec vs. system() in threads

When I need to call an external executable from within a thread, and
sometimes redirect stdout and stderr, what are the tradeoffs and/or
pitfalls of using

system(command_line);
fork(); then execXX(...);

on Solaris, AIX?
There are *no* mutexes held at that point.

I've seen some manuals that say something like
".. all threads a closed after the fork."

I have taken out any code between
fork()
execXX(...)
because Butenhof said it then will be OK.

But, I've got something working, altho sometimes it cores out but I
cannot find stepping-on memory happening.
