2016-08-22T17:35:50Z rick-mon`: Hi there - I've been hacking on a midi sequencer using ccl on embedded linux.  Everything about CCL is working out totally awesome for this application apart from one thing...
2016-08-22T17:36:53Z rick-mon`: I am interfacing with several USB serial-type devices (including /dev/midi) by just reading/writing bytes to a regular lisp stream
2016-08-22T17:37:35Z rick-mon`: however if I just yank the usb cable on one of those usb-serial devices, ccl dies completely, rather than throwing me into the lisp debugger
2016-08-22T17:38:45Z rick-mon`: is there any way to make ccl cope with usb-serial hotswapping?

2016-08-22T23:09:35Z rumbler31: I am leaking memory during a computation and I don't know how to figure out what is going on.  I read in a file, make a list of objects from the file, then create a new list from the results of various method calls on the objects.  If I repeat this process for a large set of files, memory consumption grows as a file is read in (expected) then shrinks after the objects are no longer necessary (expected) but as more and more files are read in,
2016-08-22T23:09:35Z rumbler31: the heap ends up growing to be several gigabytes.  when I pause the computation and run heap-utilization, it shows most of the heap size is taken up by cons, not the objects i've made.  if I let the process continue long enough to complete, the resulting cons is only about 1gb or so, its really just a large alist of the results of the method calls on objects, tracked across files.
2016-08-22T23:11:57Z rumbler31: my first gc tweak I made was to increase the lisp heap step size, since I know I'm inflating an 800 meg file to about 2gb, it makes sense that I should increase the heap in larger steps.  but the next part, understanding the leak, is more difficult
