On Android, Fuchsia, Linux and Mac, we generate DWARF. On Windows we should generate PDB.
We can directly produce ELF for Linux, Android and Fuchsia and Mach-O for Mac. For Windows we should support directly producing PE. We can currently indirectly produce such a DLL...
On Linux and Mac, to wait for a child process's exit code, dart:io creates a separate thread to call `wait` and separate pipes to communite the result back to epoll...
Id zone allocation is implemented by appending to a list and deletion is implemented by replacing the element with null. Repeatedly allocating and deleted id zones thus consumes memory proportional...
