* signal: Fix signal-sample.David Thompson2016-03-211-5/+9
| | | | | | | | | | | | signal-sample had a nasty nondeterministic bug where the newly created signal might actually be GC'd before it could be returned to the caller. This was able to happen because no reference to the signal was help between creating the signal and returning it.

* utils: Remove unused 'forever' procedure.David Thompson2016-02-271-4/+0
| | | | * sly/utils.scm (forever): Delete.

| | | | | This prevents some duplicated compilation when modules include other Sly modules that haven't been compiled yet.
* TODO: Mark guardian improvement as DONE.David Thompson2016-02-151-1/+1
|
* Use a single foreign object guardian.David Thompson2016-02-156-38/+109
