The problem is not actually specific to android/arm. Linux/ARM's runtime.clone set the stack pointer to child_stk-4 before calling the fn. And then when fn returns, it tries to write to 4(R13) to provide argument for runtime.exit, which is just beyond the allocated child stack, and thus it will corrupt the heap randomly or trigger segfault if that memory happens to be unmapped. While we're at here, shorten the test polling interval to 0.1s to speed up the test (it was only checking at 1s interval, which means the test takes at least 1s). Fixes #10548.

Binary Distribution Notes
If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:
export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin
See https://golang.org/doc/install or doc/install.html for more details.
