Reply from Kevin Bracey:

"There were added in RISC OS 3 a number of buffer UpCalls that are
actually called from interrupt routines. This is a Bad Thing(TM) - they
should have been events. As a result, an UpCall handler may be being
called from interrupts - I suggest you take care.

Apart from that, I can't think of any other reason why UpCalls are a bad
thing per se."
