为了扭转这一局面,一些企业采取了以下转型路径:
Add a cluster of points in one corner and watch that corner subdivide deeply while the rest of the space stays untouched. Then scatter a few points across the empty region and watch it split only where needed. The tree grows around the data.

To be clear, message passing does eliminate one important class of concurrency bugs: unsynchronized memory access. If two goroutines communicate only through channels, they cannot simultaneously mutate the same variable. But eliminating data races does not eliminate coordination failures. Deadlocks, leaks, protocol violations, and nondeterministic scheduling remain.
Real-mode programs freely execute CLI and STI to control interrupts, PUSHF and POPF to manipulate flags, INT n for DOS and BIOS calls, and IN/OUT for hardware I/O. In normal protected mode, these instructions are privilege-checked -- they execute normally if the caller has sufficient privilege, and fault otherwise. The 386 can't simply let V86 tasks execute them freely -- a DOS program disabling interrupts would bring down the whole system -- but trapping on every INT 21h call would make V86 impractically slow.,这一点在heLLoword翻译官方下载中也有详细论述
