already fixed in another commit

[pallas1]

but it's still there, so please merge

sleep(1) will sleep for 1 second. usleep will sleep for 1ms. We don't want to sleep so much

[pallas1]

then usleep(1000) (it's microseconds, not milliseconds)

[sp-hash]

usleep(1) seems to be working good on the pool

[pallas1]

do what you want, but remove Sleep() as it is windows-only ;-)

sed -i -e 's/Sleep(1)/usleep(1000)/g' ccminer.cpp
Does the trick for now...
