I didn't realize what it did; I thought it was something specific to
that test. And I thought the gdb_exit at the start of the test would
clear $gdb_spawn_id but apparently not! :) So I made a fix, basically
copied and pasted from the commit you referenced:
This commit changes the batch exit status test to detect GDB's exit
using gdb_test_multiple expecting 'eof', instead of using 'wait'.
This fixes failures reported by buildbot on Fedora 28, and also means
the testcase won't hang forever on failure as fixed in
gdb.base/quit.exp by commit 15763a09d4aea85fc3153d6746c040dd48565637.
Is this ok to commit?
Thanks,
Gary

* gdb.base/batch-exit-status.exp: Use gdb_test_multiple and expect
'eof' before 'wait -i'. Use remote_close and clear_gdb_spawn_id.
