It sets the default timeout interval for Regexp matching in second. nil means no default timeout configuration. This configuration is process-global. If you want to set timeout for each Regexp, use timeout keyword for Regexp.new.
Example
Regexp.timeout = 1 /^a*b?a*$/ =~ "a" * 100000 + "x" #=> regexp match timeout (RuntimeError)
