I just downloaded and tested 1.4.2 and it did not hang my system:

Without X: 14 of 122 tests did not behave as expected (2 XPASS)

FAIL: clip-operator
FAIL: font-matrix-translation
FAIL: glyph-cache-pressure
FAIL: operator-clear
FAIL: operator-source
FAIL: select-font-face
FAIL: show-text-current-point
FAIL: text-antialias-gray
FAIL: text-pattern
FAIL: text-rotate
FAIL: unbounded-operator
FAIL: ft-text-vertical-layout-type3

XPASS: surface-pattern-scale-down
XPASS: surface-pattern-scale-up

With X: 18 of 122 tests failed

FAIL: clip-operator
*FAIL: dash-scale
*FAIL: dash-state
FAIL: font-matrix-translation
FAIL: glyph-cache-pressure
FAIL: operator-clear
FAIL: operator-source
*FAIL: pixman-rotate
*FAIL: random-intersections
*FAIL: rotate-image-surface-paint
FAIL: select-font-face
FAIL: show-text-current-point
*FAIL: source-clip-scale
FAIL: text-antialias-gray
FAIL: text-pattern
FAIL: text-rotate
FAIL: unbounded-operator
FAIL: ft-text-vertical-layout-type3

I notice that extend-reflect is not in the test suite any more.

Is there anything I can do to help resolve some of these failures?
