#1 mutex::lock() with timeout under pthread

[Vlad ROMASCANU]

Easy to do (loose syntax):

while(true) {
firstcheck = -1, lastcheck;

if (trylock())
return SUCCESS;

if (lastcheck == -1) {
firstcheck = getmillis(); // assume getmillis is
// expensive so we only
// do it if first trylock
// fails
yield(); // ...or sleep 1ms
} else {
thischeck = getmillis();
if (thischeck - firstcheck > timeout)
return TIMEOUT;

yield();
}
}
