- Fix bugs in kDos2Errno definition - malloc() should now be thread safe - Fix bug in rollup.com header generator - Fix open(O_APPEND) on the New Technology - Fix select() on the New Technology and test it - Work towards refactoring i/o for thread safety - Socket reads and writes on NT now poll for signals - Work towards i/o completion ports on the New Technology - Make read() and write() intermittently check for signals - Blinkenlights keyboard i/o so much better on NT w/ poll() - You can now poll() files and sockets at the same time on NT - Fix bug in appendr() that manifests with dlmalloc footers off
