Changed the non-IRQ checking interval

[Manawyrm]

for some reason the interval was set to 0ms, which lead to an infinite loop of memory allocations quickly resulting in a segmentation fault.

Hmm, interesting. The DOM spec enforces a minimum timeout of 4ms regardless of what is passed, but maybe node.js handles differently. Have you tried it with a 1ms timeout? That might be the best compromise between data latency and runaway checks…
