The Think C manual says (page 75):
"When the Separate STRS option is on, THINK C uses a 4 byte absolute
address to access the string literals and floating point constants."

Speculation:

Since the string literals and fp constants are loaded into the heap
(and locked), and since any reference to things in this heap object
are not absolute until that point, then all of those absolute
references must be set then, after the literals are loaded.  This
also means (since code is being changed) that they have to be re-set
every time a code segment with references to the string literals is
unloaded and loaded, which means either Think C is keeping careful
tabs on the segment loader (a patch?) or the segment loader is actually
doing the work.

If ANY of this is correct, my question is: Where, exactly, do the
absolute references get set?  Thanks.
