Let me rephrase: In what kind of environment would "hairy"
*necessarily* imply "GC-causing"?

(There used to be a version of Scheme 48 where the equivalent of
SCHEME_EXTRACT_LONG could cause a GC because it could do a callback.
This was an implementation convenience, not a necessity, and it's gone
now.)
