Hello Bryan,

Thanks for those clarifications.

Is that something required by POSIX (I could not find any documentation 
about that) ? Or is it a limitation (or bug) of our implementation ? 
Other shells -mostly- do not behave that way (see my original post).

Unfortunately, in my case, spawn would have to be called from a 
sub-process already forked (from a background function, executed as a 
child process) ; so that wouldn't work either. Anyway, thanks for the 
hint :)
