New Comment:
I submitted bug #22099. If it's just a duplicate of this, I'm assuming
you think it's fixed. It's not. Here's a backtrace and I did the same
thing you asked the last guy
to do by printing the contets of frame 2. Got a really
odd result.

The select call that ensures all data is flushed to the remote server
never times out.
#22099 is a dup of this bug.

Could you do that again, but this time type the following after you
type "bt" (also in gdb):
frame 2
print *stream

I was using 4.3.0 on the machine running the "server" test script (but
since that script is merely to aid in testing the bug in the "client"
script, I didnt think it mattered). The machine running the "client"
script - the one experiencing the bug - was running a stable snapshot
compiled last night. Nontheless, I just re-compiled with the latest
stable today, ran again, and managed to generate a bt in the process:
