script to reproduce

Hi,

The Net::Curl::Multi interface is failing when using both the proper
event-driven approach (fdset/timeout) and the polling workaround.
All multi-mode operations fail with the error "Operation was aborted by an
application callback", while the synchronous Net::Curl::Easy interface works
correctly.


Here is a regression script that demonstrates the issue by attempting to fetch
multiple URLs in parallel using three different approaches:

1. Synchronous mode (perl curl-multi.pl): Works correctly
2. Multi mode with polling (perl curl-multi.pl --multi --multifix): Fails with
callback error
3. Multi mode with fdset (perl curl-multi.pl --multi): Fails with callback
error

The error suggests an issue with callback handling
(CURLOPT_HEADERDATA/CURLOPT_WRITEDATA) when used with Net::Curl::Multi.
The same callbacks work fine in synchronous mode with Net::Curl::Easy (so not
related to libcurl).

Regards,
Olivier
