nginx-0.1.5-RELEASE importrelease-0.1.5

    *) Bugfix: on Solaris and Linux there may be too many "recvmsg()
       returned not enough data" alerts.

    *) Bugfix: there were the "writev() failed (22: Invalid argument)"
       errors on Solaris in proxy mode without sendfile. On other platforms
       that do not support sendfile at all the process got caught in an
       endless loop.

    *) Bugfix: segmentation fault on Solaris in proxy mode and using
       sendfile.

    *) Bugfix: segmentation fault on Solaris.

    *) Bugfix: on-line upgrade did not work on Linux.

    *) Bugfix: the ngx_http_autoindex_module module did not escape the
       spaces, the quotes, and the percent signs in the directory listing.

    *) Change: the decrease of the copy operations.

    *) Feature: the userid_p3p directive.
