I don't see the loophole (in the rules) at all. See 2 USC Sec. 641(e)(2). Not to say the rules are sacrosanct, but following the rules does not result in an indefinite debate time to address an indefinite number of amendments.

2 USC Chapter 17a - Congressional Budget and Fiscal Operations

Sec. 641. Reconciliation
(e) Procedure in Senate
(1) Except as provided in paragraph (2), the provisions of section 636 of this title for the consideration in the Senate of concurrent resolutions on the budget and conference reports thereon shall also apply to the consideration in the Senate of reconciliation bills reported under subsection (b) of this section and conference reports thereon.
(2) Debate in the Senate on any reconciliation bill reported under subsection (b) of this section, and all amendments thereto and debatable motions and appeals in connection therewith, shall be limited to not more than 20 hours.

Another point worth noticing, is that the budget process is Byzantine. A morass imposed on the Congress, by the Congress.

(2) Debate in the Senate on any reconciliation bill reported under subsection (b) of this section, and all amendments thereto and debatable motions and appeals in connection therewith, shall be limited to not more than 20 hours.

The loophole is that debate is limited, but not the amendments themselves. So the Senate may have to immediately vote on each amendment rather than debate it, but if there are hundreds or thousands of amendments, that keeps chewing up the clock. Every roll call vote will take at least 15 minutes. Also, if unanimous consent is not given, I believe the text of each amendment would have to be read.
