changes in sbcl-1.2.16 relative to sbcl-1.2.15:
* enhancement: by default, timers with a repeat interval do not "catch up"
by repeatedly calling their function after a clock discontinuity such as a
suspend and resume cycle
* bug fix: correctly restore multiple values on the stack in the presence of
alien calls. (lp#1489590)
* bug fix: MAKE-STRING-OUTPUT-STREAM enforces that :ELEMENT-TYPE
is a subtype of CHARACTER.
* bug fix: an EQL method specializer no longer causes garbage retention
if there are no extant methods using the specializer. (lp#492851)
