Yes, and that's what the line referred to in brlapi_server.c calls.

I'll try valgrind next. Running under electric fence with the -N option was
easy, and it triggered the following after the braille display had been in use
for only about ten seconds. It's another call to brl_writeWindow().
(gdb) bt
