As per my grant conditions, here is a report for the November period.
Nearly all the month was spent on one bug, which was to make PerlIO minimally re-entrant (so it doesn't segfault when a signal handler closes a file that is being read for example). This took so long, partly because it's an area of perl I was completely unfamiliar with, and partly because the code was very resistant to having re-entrancy retroactively bolted onto it.
Note that the my grant has recently "been extended":http://news.perlfoundation.org/2010/12/fixing-perl5-core-bugs---grant.html by a further 400 hours, to a total of 900 hours.
Over the last month I have averaged 12.7 hours per week. Over the 38 weeks of the grant so far, I have done 512 hours, averaging 13.5 hours per week. There are 388 hours left on the grant.
