Sorry to be returning the favor so soon, but this patch causes 'make check' in
the texinfo source tree to hang. I don't have time at the moment to try to
produce a simple test case, so here's a complicated way to reproduce the problem:
1. Clone the texinfo git repo:
$ git clone https://git.savannah.gnu.org/git/texinfo.git
2. Build texinfo:
$ cd texinfo
$ ./autogen.sh && ./configure # Maybe CFLAGS='-g -O0' for debugging
$ make
3. Test the standalone info reader:
$ cd info
$ make check
It hangs while running the test t/malformed-split.sh, leaving a ginfo process
and a pseudotty process running, with ginfo trying to close a pty slave.
Note that this test uses both ptys and fifos, so there's always a chance that
this is another fifo bug. But reverting your patch fixes the problem, so I
think it's probably a pty bug.
