ST_Buffer is slow at being interrupted

[strk]

As shown by running:

regress/run_test.pl -v regress/core/interrupt_buffer

The buffer code (at least as of GEOS 3.12.0dev-CAPI-1.18.0) is slow at being interrupted:

-buffer interrupted on time
+buffer interrupted late: 00:00:13.774277

The statement_timeout in the test is 100ms, the operation interrupts after more than 13 seconds. This is likely to be caused by GEOS itself

Fixed upstream, the problem was ONLY in the still unreleased GEOS-3.12.0dev, closing
