Ryan C. Gordon adb91fd3db process: Don't use vfork() on Apple platforms. 
They want you to use fork(), which is almost-identical in their implementation.
They mark vfork() usage with a big scary deprecation warning.

Sam Lantinga afee27a530 Make sure stdio handles are in blocking mode 
Standard I/O doesn't work well with non-blocking handles, so make sure any pipes are in blocking mode before launching child processes.

Sam Lantinga 00385951a1 Use file descriptor I/O for process pipes 
Use low level non-blocking I/O for process pipe streams. This may fix issues with data not getting through the pipe occasionally.

Sam Lantinga a90ad3b0e2 Removed SDL_bool in favor of plain bool 
We require stdbool.h in the build environment, so we might as well use the plain bool type.

If your environment doesn't have stdbool.h, this simple replacement will suffice:
typedef signed char bool;

Sam Lantinga e673479449 Removed SDL_WriteProcess() 
This had the unfortunate side-effect of blocking if you tried to write too much. Instead you can use SDL_GetProcessInput() and handle SDL_IO_STATUS_NOT_READY as needed.

Sam Lantinga 90e01040c5 Added thread-safe environment functions 
Also marked the existing functions as unsafe, as they can cause crashes if used in multi-threaded applications.

As a bonus, since the new functions are hashtable based, hint environment lookups are much faster.
