New Revision: 25633

Modified:
   trunk/src/gc/dod.c

Log:
[GC] After the mark phase of a GC run, sweep the STRING/Buffer pools too so
that we can free allocated memory for string contents and reuse allocated
headers.

Maybe our memory use will go down again now.

Fixes RT #47704, reported by Mehmet Yavuz Selim Soyturk.
