open3 and mod_perl

[Rasoul Hajikhani]

Hello folks,
I am writing a web interface for the GPGP module that would allow users
to create a new public and private key and adds them to the corporate
key ring. I will be useing IPC::Open3 and IO::Select to "control" stdin
and stdout of GPGP. Are there any issues that I should be aware w/ these
packages under mod_perl? Any suggestions and comments would be greatly
welcomed.
Thanks in advance
