1.4 signal-based resolver timeouts
1.5 get rid of PATH_MAX
1.6 Modified buffer size approach
+ 1.7 Detect when called from witin callbacks
2. libcurl - multi interface
2.1 More non-blocking
Dynamically allocate buffer size depending on protocol in use in combination
with freeing it after each individual transfer? Other suggestions?
+1.7 Detect when called from witin callbacks
+
+ We should set a state variable before calling callbacks, so that we
+ subsequently can add code within libcurl that returns error if called within
+ callbacks for when that's not supported.
