Do i not understand timeout()?

[sckott]

is this the correct behavior?

# no time out
res <- GET("http://google.com", timeout(1))

# no time out
res <- GET("http://google.com", timeout(0.5))

# no time out
res <- GET("http://google.com", timeout(0.1))

# timed out
res <- GET("http://google.com", timeout(0.01))
Error in function (type, msg, asError = TRUE)  : 
  Operation timed out after 14 milliseconds with 0 bytes received

# timed out
res <- GET("http://google.com", timeout(0.001))
Error in function (type, msg, asError = TRUE)  : 
  Resolving timed out after 4 milliseconds

# no time out
res <- GET("http://google.com", timeout(0.0001))

# no time out
res <- GET("http://google.com", timeout(0.00001))

...and so on

curl docs http://curl.haxx.se/libcurl/c/CURLOPT_TIMEOUT.html says setting to 0 means no timeout. So is a decimal that's sufficiently small considered essentially 0?
