Similar to #10934, but the system panicked in usleep() instead.
This happened on hrev47380, on a gcc2 hybrid running in VMWare Player 6.0.1.
I was running the tests for the Golang toolchain; I left the computer for a while, and when I returned the display was frozen.
The last window displayed was an "application has crashed" dialog for one of the Golang tests.
After attaching a serial console, the backtrace showed that the system had panicked with the message "failed to acquire spinlock %p for a long time".
Attached is the backtrace from the serial console.
