While running a Go program that uses Cgo, I noticed a surprising number of
threads. I believe the code below demonstrates what I'm seeing minus (what
I hope are) extraneous details.
package main
// #include <unistd.h>
import "C"
func main() {
for {
C.nanosleep(&C.struct_timespec{tv_sec: 0, tv_nsec: 10000}, nil)
}
}
If I run this program with GOMAXPROCS=1, I see 4 threads (as reported by
top). I was expecting that number to be closer to 2.
I'm compiling with go 1.11.1 on linux/amd64.
Michael.
