AFAIK, busybox still forks whereever a regular POSIX shell forks, so if the 
amount of forks is the problem, AFAICT busybox will resolve absolutely nothing.

A shell which emulates POSIX process handling in-process and uses direct 
builtin function calls for commands like sed rather than forking a new process 
(even a new process of itself as busybox appears to be doing) could work, but 
would that be maintainable? And what about parallelism: threads? Pipes and the 
like would also have to be emulated by special-case code to become as efficient 
as a real programming language, which would drive maintainability even further 
down (imagine having to implement memory-to-memory, memory-to-file, 
file-to-memory and file-to-file versions of all tools like sed, grep etc.).
