Subject: When a recycled frame has more local+stack slots than needed,
X-Git-Tag: v1.5a1~431
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=747596a4917cc8924519bdee081a894ebcb0e059;p=python

When a recycled frame has more local+stack slots than needed,
give the extra slots to the stack rather than than forgetting about
them (this reduces the number of reallocs done).
