| Fixed In Version: | Doc Type: | Bug Fix | |
| Doc Text: |
Previously, when a command was substituted using backquotes, a second, redundant fork() system call was performed. This could have caused problems when a child process needed to find the PID of its tcsh parent. With this new package, only one fork() is performed.
