TPF Grant November 2010 report
Message ID:
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 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.

Report for period 2010/11/01 to 2010/11/30 inclusive
