Jilles Tjoelker 4f6e4215a0 Do not fork for a subshell if it is the last thing this shell is doing ... (EV_EXIT). The fork is still done as normal if any traps are active. In many cases, the fork can be avoided even without this change by using {} instead of (), but in practice many scripts use (), likely because the syntax is simpler. Example: sh -c '(/bin/sleep 10)& sleep 1;ps -p $! -o comm=' Now prints "sleep" instead of "sh". $! is more useful this way. Most shells (dash, bash, pdksh, ksh93, zsh) seem to print "sleep" for this. Example: sh -c '( ( ( (ps jT))))' Now shows no waiting shell processes instead of four. Most shells (dash, bash, pdksh, ksh93, zsh) seem to show zero or one.
