iOS: 18.1.1

Describe the bug

Running two commands from ios_system.framework at the same time (in separate windows) will result in a hang. I first ran into this running curl in two windows (a relatively contrived example as I was testing something out, but something that could happen in normal use.)

Then I noticed that if I were to curl in one window and ls in another, I got a hang. This also happens with other commands from the ios_system.framework: if I cat and ls, cat and curl, etc.

I understand that there are some limitations in ios_system.framework and perhaps this is one of them. If so, perhaps there should be a lock on running any of these commands at the same time.

I tried this in a-shell and I also get a crash when I run two curl processes at the same time, but I can use cat and ls, etc. as expected.

Thanks! This shouldn't happen though. I will review.

Also noticed that if you then try to do a Ctrl-C there, then everything goes nuts.
