It looks like this regressed due to commit 
073da412a139e317959f56e359ed12de726a0a35, which fixed bug#59545. I'll 
take a look at resolving this.

The I/O refcounting code in Eshell is pretty tricky. I have a WIP patch 
that will hopefully make it less error-prone, but I'll worry about that 
later...
