                Things that could be nice to do in the future

 Things to do in project cURL. Please tell us what you think, contribute and
 send us patches that improve things!

 Be aware that these are things that we could do, or have once been considered
 things we could do. If you want to work on any of these areas, please
 consider bringing it up for discussions first on the mailing list so that we
 all agree it is still a good idea for the project!

 All bugs documented in the KNOWN_BUGS document are subject for fixing!

==============================================================================

1. libcurl

1.2 More data sharing

 curl_share_* functions already exist and work, and they can be extended to
 share more. For example, enable sharing of the ares channel and the
 connection cache.

1.3 struct lifreq

 Use 'struct lifreq' and SIOCGLIFADDR instead of 'struct ifreq' and
 SIOCGIFADDR on newer Solaris versions as they claim the latter is obsolete.
 To support IPv6 interface addresses for network interfaces properly.

1.4 signal-based resolver timeouts

 libcurl built without an asynchronous resolver library uses alarm() to time
 out DNS lookups. When a timeout occurs, this causes libcurl to jump from the
 signal handler back into the library with a sigsetjmp, which effectively
 causes libcurl to continue running within the signal handler. This is
 non-portable and could cause problems on some platforms. A discussion on the
 problem is available at https://curl.haxx.se/mail/lib-2008-09/0197.html

 Also, alarm() provides timeout resolution only to the nearest second. alarm
 ought to be replaced by setitimer on systems that support it.

1.5 get rid of PATH_MAX

 Having code use and rely on PATH_MAX is not nice:
 http://insanecoding.blogspot.com/2007/11/pathmax-simply-isnt.html

 Currently the SSH based code uses it a bit, but to remove PATH_MAX from there
 we need libssh2 to properly tell us when we pass in a too small buffer and
 its current API (as of libssh2 1.2.7) doesn't.

1.6 Modified buffer size approach
