v1 was here: https://www.redhat.com/archives/libguestfs/2019-September/msg00100.html In v2 I've changed the patch so it avoids calling realloc at all in this case. The patch is a bit longer this way. But I don't see any other alternative if we are to avoid having a "realloc wrapper" of some kind that we use everywhere, which I guess we should avoid because it makes plugins

OpenSSH still has this feature, SSH-1.2.27 no longer has it. Admittedly it can be useful sometimes, even though I'd prefer this to be done using a trivial shell wrapper, which would be the UNIX way of doing things. Not being able to call OpenSSH's ssh by another name (say ``ssh1'') can get in the way when having to maintain two versions of ssh in parallel because the ``ssh ->

Patch 2 certainly allows you to set the thread model. However patch 3 shows that if you set it to nbdkit.THREAD_MODEL_PARALLEL it will crash. If you look closely at the stack trace (attached below) you can see that ignoring threads which are in parts of nbdkit unrelated to Python: Thread 4: In pread, waiting in time.sleep(). This thread has released the GIL. Thread 2: Started to
