"I find the fact that RISC OS stops as soon as it does any disc IO operations one of the most glaring difference when moving from other operating systems."
Thats funny, because I find the fact that this PC (Windows 2000) regularly stops (for about a minute) for no apparent reason the most glaring difference between the two computers I use regularly.
Maybe most win2000 PCs don't do this, but my [work] one does. Presumably it is using PMT, so clearly it isn't a panacea. At least, M$' implemention isn't.

How secure is fudgehole against the same sort of thing happening?
