} With latest sources, I'm getting a hang up on A05:

Yes, this used to happen intermittently for me but with the latest
revision from git it now happens very consistently for me.

I have one shell stopped (job state "T", as if it got SIGTTOU or SIGTTIN)
here:

#1  0x00000000004a5225 in settyinfo (ti=0x7fff15c1ecc0) at utils.c:1626
#2  0x00000000004a654b in read_poll (fd=0, readchar=0x7fff15c1ef78, polltty=1, 
    microseconds=5000000) at utils.c:2332
#3  0x0000000000423efb in bin_read (name=0x2b528371bbb8 "read", 

And its child stopped here:

#0  0x00002b5282b0de70 in __close_nocancel ()
    at ../sysdeps/unix/syscall-template.S:82
#1  0x000000000042d92a in execpline2 (state=0x7fff15c1ff70, pcode=355, how=2,

If I back out the changes to polltty handling in read_poll() from 34365
(git commit 4688de16772beffc315bbf765475a2932cbd8628) it works again.
