One problem that I encountered: FastCGI claims that a CGI program can be
changed to FastCGI with the addition of a line or two of code.  This is
not quite true: a valid CGI program can call exit() at one or more
points in the code, and this is sometimes a convenient way to handle the
flow of control in the program.

Of course, using exit() in a FastCGI program is a BAD idea, and the CGI
program would have to be massaged to (1) not call exit() (easy) and (2)
re-route the flow of control appropriately (not quite that easy).

Programs with exit()s will give lots of problems when used as FastCGI
programs: truncation of pages, server error messages, high server loads
as the server repeatedly re-runs the programs as they exit, etc.
