Hm... I think the problem is more serious than that.  My builds are 
failing on any sleep statement (that is, /bin/sleep, the executable).

Indeed, '/bin/sleep 1' causes it to go off into lala-land, and truss is 
of no help.

The following test executable waits forever:

#include <unistd.h>
int main() { sleep(1); return 0; }
I am running on VMware, though.
