The essential idea here is that a handler thread only needs to hold a lock on the global node table while it is manipulating nodes. The actual I/O operation is then performed without holding any locks. By default, we use 2 threads but this can be configured on the command-line. Work is sheduled somewhat arbitrarily by the handler threads. Whichever thread happens to read() the next request first wins the right process it. This policy is very simple but potentially wastes threads when there isn't much work to be done. We can always improve this later if needed. Change-Id: Id27a27c2c9b40d4f8e35a6bef9dd84f0dfacf337 |

The system/ directory is intended for pieces of the world that are the core of the embedded linux platform at the heart of Android. These essential bits are required for basic booting, operation, and debugging. They should not depend on libraries outside of system/... (some of them do currently -- they need to be updated or changed) and they should not be required for the simulator build. The license for all these pieces should be clean (Apache2, BSD, or MIT). Currently system/bluetooth/... and system/extra/... have some pieces with GPL/LGPL licensed code. Assorted Issues: - pppd depends on libutils for logging - pppd depends on libcrypt/libcrypto - init, linker, debuggerd, toolbox, usbd depend on libcutils - should probably rename bionic to libc
