I'm just wondering about the stack size limit (e.g. for regexp search, search.c). Would it make sense to make it any bigger, given that machines nowadays are more powerful and have more memory, or do you consider that pretty much all such stack overflows (e.g. for regexp matching) are just due to poorly chosen regexps? Again, just wondering if it might be appropriate (time) to bump the stack limit. (No, I don't have a particular use case or regexp in mind.)
