Ditto. It's often those embarrasing moments when your own software
kills a system that you realise that that quick bit of code you
stuck in wasn't all that appropriate.
 
Acorn themselves weren't immune. It's really annoying how much
memory is unexpectedly trashed by OSWORD 127, and OSWORD 14 on a
Compact with NetFS active.
