timeout(sec, klass = nil) private

Perform an operation in a block, timing it out if it takes longer than sec seconds to complete.


Number of seconds to wait for the block to terminate. Any number

may be used, including Floats to specify fractional seconds.


Exception Class to raise if the block fails to terminate

in +sec+ seconds.  Omitting will use the default, Timeout::Error

The block will be executed on another thread and will be given one argument: sec.

Returns the result of the block if the block completed before sec seconds, otherwise throws an exception, based on the value of klass.

Note that this is both a method of module Timeout, so you can include Timeout into your classes so they have a #timeout method, as well as a module method, so you can call it directly as Timeout.timeout().
