# Precedence:
#
# - The FORCE_FFI_YAJL env var takes precedence over everything else, the user
# theoretically knows best
# - Java always gets ffi because jruby only supports ffi
# - There is a conflict between loading libyajl 1.x and 2.x in the same VM
# process (on a fundamental basis, simply guru medidate about how the
# c-symbols work if you load both libs). For some reason the ffi interface
# seems to work fine sometimes (i'm not sure how) so we fall back to that--
# this is much more likely to be converted into a raise than to have the warn
# dropped, so don't bother asking for that.
# - Then we try the c-ext and rescue into ffi that fails
#
