Not very serious. Interrupt handling might be a bit messed up, in
particular some interrupts (CTRL-C) might be seen twice: once by the
default Python handler (`raise KeyboardInterrupt`) and once by the special
Sage handler (written in C).
The line
{{{
signal.signal(signal.SIGINT, sage_python_check_interrupt)
}}}
is mainly used to ensure that only the Sage signal handler is used.
But this will certainly have no consequences beyond interrupt handling.
