Every claim below was made in this piece, quoted word for word and numbered in the order the piece makes them, so you can read it there rather than take our word for it. The sentence above each quote is our reading of the claim, not their wording. Each quote was checked against a stored copy of the page at build time; where the two differ, the quote is the fact.

Our reading
Register-based virtual machines can run faster than stack-based virtual machines despite needing larger instruction encodings.

Their wordsRegister-based virtual machines avoid the push and pop operations usually surrounding other instructions, reducing code size, but in several cases also increases speed of execution (compared to stack-based virtual machines).
Our reading
Cooperative multitasking suits coherent, specialized systems better than general-purpose operating systems.

Their wordsThese systems often benefit from cooperative multitasking, in particular coherent, specialized systems (unlike operating systems which are general by nature).
