In fact I don't understand alarm(...) at all. Maybe it works better on
linux or older OS X releases, but on the OS X machines to which I have
access, it feels broken. If I do:
sage: alarm(0.3)
then after 0.3 seconds I see a message
KeyboardInterrupt escaped interact()
That's fine. But then the next command I issue tends to get interrupted:
┌────────────────────────────────────────────────────────────────────┐
│ SageMath version 10.3.beta2, Release Date: 2023-12-13 │
│ Using Python 3.11.6. Type "help()" for help. │
└────────────────────────────────────────────────────────────────────┘
┏━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┓

sage: alarm(0.3)
sage:
KeyboardInterrupt escaped interact()
sage: identity_matrix(10)
---------------------------------------------------------------------------
AlarmInterrupt Traceback (most recent call last)
Cell In[2], line 1
----> 1 identity_matrix(Integer(10))
...
Why? The alarm should have already happened. As I said before, if I exit
Sage, then it does not do so gracefully. Furthermore, if instead of exiting
I issue a second alarm, Sage crashes:

Something seems to be pretty broken.
