ctrl-c doesn't exit for several seconds

[ns-cweber]

When I'm searching a large directory with many subdirectories and decide to cancel my search via ctrl-c, the operation hangs for 10-30s (presumably correlated to the number and size of search files). This is a real usability pain point.

OS: OS X 10.11.6
Go version: go version go1.7.1 darwin/amd64
Reproduction instructions:

1. Clone https://github.com/golang/go
2. cd into the repo
3. time pt golang and immediately ctrl+c
4. Observe 6+ seconds before the operation terminates

Repeating the same steps with ag shows a .2 second termination time, and that's probably mostly the time it takes me to press ctrl+c.

[NOTE] the platinum searcher does not handle any signals.

• Your environment, OS, go version etc
• How to reproduce this issue ? (Searching for Linux kernel tree ?)

I've updated the original issue.

I cannot reproduce. It looks you use older Go. Could you try again after updating go and re-compiling the platinum searcher.

My Environment is

• Go : go version go1.7.4 darwin/amd64
• OS : macOS 10.11.6
• Latest the platinum searcher built from source code.

No change. :(

My pt commit sha is 509368a if that helps.
