Something like that, yes.

When you derive the itch function for toom66, you need to take into
account that when recursing, you sooner or later get a multiplication
below the toom66 threshold and recurse to toom44, and then the scratch
space needed for that call is at most
toom44_itch(MPN_TOOM66_THRESHOLD).
