Question about IO::Select can_read block

[Lin Tianshan]

Hi,

  I wrote a single thread http server. When browsing from different computer,it works 
very well. But when I open two browser to visit the http server,sometimes it will 
block and all other connection will block too.I trace the program and find out that 
when coming to $sel->can_read,server blocked. As I know,$select->can_read block when 
no data can be read,but there have many connection at that time.

can any one help me?
