d05806450a Avoid compiler complaints about dynamic array syntax. This is no better code, bu 
t it's less sensitive to compile options.

c1108834c1 In this emergency, increase the buffer size by a factor rather than only by a constant amount - because if this arises because of an overlong increment being broken down into littler bits, we would end up doing it again and again, which is much more expensive. This makes a huge performance difference in cases where a time map ends up mapping very little input into a great expanse of output 2020-09-22 10:35:50 +01:00

661a1d05eb It appears this may be all we need - apparently the occasional odd extra sample (due to incremental rounding) added up and eventually overran the filter. I believe +1 is perfectly good here, but we can afford to be more accommodating just in case 2020-09-16 17:52:33 +01:00

b68f500e2d We don't actually use clock_gettime here. Which is fortunate, because its arrival in OSX 10.12 would pose a slightly tricky code target consistency question 2018-02-02 09:12:07 +00:00
