Re: Unaligned word-sized reads on ByteArray#

I noticed that indexWordArray# only allows for aligned reads (by forcing the offset to be in words, rather than in bytes.) Is it possible to perform unaligned reads on a ByteArray# e.g. going via Addr#? There's the byteArrayContent# primitive but I don't know how to force the ByteArray# to stay pinned in memory while performing my reads. The ByteArray# is not guaranteed to be pinned in my case.

It seems like I should be able to use (the undocumented) touch# function to achieve this. Is that the case? Johan
