+Subject: [PATCH] rpm/rpmio.c: restrict virtual memory usage if limit set
+
+A solution to avoid OOM situation when the virtual memory is restricted
+for a user (ulimit -v). As the lzopen_internal function is run in parallel
+one instance per CPU thread the available virtual memory is limited per
+CPU thread.
+
+Upstream-Status: Pending [merge of multithreading patches to upstream]
