Description
setrlimit(RLIMIT_NOFILE, RLIM_INFINITY) appears to cause serious problems for ksh (shell) due to a bug in ksh itself, however, this is still a regression from user's point of view and needs to be fixed.

The easiest fix at this moment is simply to back out the original fix, which triggers the issue in ksh.

I tested the original change with the default terminal on Mac, i.e. "zsh" and did not think to try the other ones.
