Existing movable allocations will also be moved to defragment the supervisor heap and ensure that the next VM run gets as much memory as possible for the GC heap. By itself this breaks terminalio because it violates the assumption that supervisor_display_move_memory() still has access to an undisturbed heap to copy the tilegrid from. It will work in many cases, but if you're unlucky you will get garbled terminal contents after exiting from the vm run that created the display. This will be fixed in the following commit, which is separate to simplify review. 2020-11-27T21:03:37+00:00 Dan Halbert halbert@halwitz.org 2020-11-27T21:02:17+00:00 urn:sha1:e308a9ec1134412f6194358790176d17b0724ef1 2020-11-25T22:52:06+00:00 Dan Halbert halbert@halwitz.org 2020-11-25T22:52:06+00:00 urn:sha1:ef0830bfe241b544b05bd3081f5bba03af57fe0d
