the problem: hashcash always takes a second on windows.
a guess at the cause of this problem: running in verbose mode, it takes this
time "initial benchmark" finishes. also, it appears to always do this benchmark
when minting. a benchmark itself (-s), too, is fast on linux, and slow on
windows. a guess to why: CLOCKS_PER_SEC being 1000000 on linux, and a much lower
value (1000?) on windows. and the test running for a given number of clocks
(such as 1000). windows *can* have >1000000 clocks/sec timestamp accuracy, if
you use the "performance counter" (queryperformancefrequency,
queryperformancecounter). one could write a small "time" library which exposes
the right things, and conditionally use it in windows instead of the normal one.
