-Summary: runtime locks up on a simple, non-threaded program
+Summary: GC enters infinite loop on some allocation patterns
 I've run into an annoying deadlock while hacking on my heap profiler.  The
 deadlock is in program that reads and analyzes the file containing the GC
 history.  It is a simple, single-threaded program than just opens the
 history file and parses it using a BinaryReader.

 Paolo, can you try to reproduce this?

+This is not a lock up: the GC enters a state where it needs
+more memory, it runs a GC that fails to clenup enough room, but it
+doesn't expand the heap.
+As a temporary workaround you can set the env var
+I'm investigating further.
