This is a small benchmark measuring fmt.Sscanf() abilities to parse an integer, vs. strconv.ParseInt(). Run with "go test -bench=." (no quotes) and see for yourself; results are amazing... Sscanf() is 40 times slower parsing a simple integer than ParseInt().

My idea of a process supervisor, using locking to react immediately to supervised processes deaths. As locks are guaranteed to be released when the process ends, no matter the reason, this can as easily detect crashes or processes killed with SIGKILL. It also writes pid files, though that's a bonus feature, not strictly required.

Regular expressions are flexible, but that obviously comes with a time penalty. If you need to check for very specific cases, you may be better off writing the function yourself. Check this out...
package main
import (
"regexp"
"testing"
)
func matches(str, pattern string) bool {
p, s := 0, 0
matches := true
