Problem & expected behavior (under 200 words)

I'm not aware of how tsx works internally, but apparently it breaks at least some forms of inter-process communication. I setup a child process to have a stream (fd 3) to talk with it's parent, but that becomes unusable when using tsx. Spent quite a bit of time to track the issue to tsx actually ^_^

I don't know if this is easily fixable, but at least it should be documented somewhere.

Bugs are expected to be fixed by those affected by it
