select uses 1000 microsecond timeout

Why is this so short?

I believe that this effectively turns the select into polling with such a short timeout. Can this number be increased, or am I not understanding how the event loop works?

No, your understanding of how the event loop works is correct. #22 hypothesized that RXTX originally used a 100ms timeout on the select(2) call, but I've been unable to locate whatever commit changed that. Either way, this has been increased again as of ea5c096 and #48.

Thanks for bringing this up.

Awesome! I completely forgot that I opened this.
