This would seem to be a fairly expensive operation, since each invocation requires a complete load of perl.exe, and the resulting compilation of the script. You will probably speed up the overall process, but with a heavier load cost to the system.

I don't know what the expense of changing to Win32::Process would be, but it's probably less than using eval() to spawn the process.

As much as I like Windows, this one paragraph makes for a lot of frusteration:
One of the largest areas of difference is in the process model. UNIX has fork; Win32 does not. Depending on the use of fork and the code base, Win32 has two APIs that can be used: CreateProcess and CreateThread. A UNIX application that forks multiple copies of itself can be reworked in Win32 to have either multiple processes or a single process with multiple threads. If multiple processes are used, there are multiple methods of IPC that can be used to communicate between the processes (and perhaps to update the code and data of the new process to be like the parent, if the functionality that fork provides is needed).
