Yes, I think so. We have not yet tried hard to persuade those tools to
cooperate, but I find it hard to believe that they cannot be handed a
source string in an externally supplied buffer. At worst, we might find
that we can only promise > 64K query length when using a bison-generated

yaccs).
lex may or may not be worth worrying about --- the buffer size limit it
would impose would be for a single token, I believe, not for the whole
query.
