[mp2] $r->read() return negative value.
-------------8<---------- Start Bug Report ------------8<----------
1. Problem Description:
I'm using CGI.pm 3.05 with mod_per 1.99 and Apache 2.0.40 on a Red
Hat Linux 9 box. When uploading a large file to my perl script,
If I abort file transfer by close the browser, the httpd child
process who process this request will run out of memory.
Whe i trace into the CGI.pm, I found in mod_perl2 the $r->read will
return -1 instead of 0 when user stop a POST submit.
is't a mod_perl bug?

Have you read my reply to your question, Wood Chen? I've asked you to
upgrade your Apache/mod_perl setup to 2.0.50/1.99_14 and only if the
problem persists then submit a new bug report.
Thank you.
