<p>The thing I miss mostly in asyncore is a system for calling a function after a certain amount of time without blocking. This is crucial for simple tasks such as disconnecting a peer after a certain time of inactivity or more advanced use cases such as <a href="http://code.google.com/p/pyftpdlib/source/browse/tags/release-0.6.0/pyftpdlib/ftpserver.py#1048">bandwidth throttling</a>.</p>
<p>This recipe was initially inspired by Twisted's internet.base.DelayedCall class:</p>

<p>...then included into pyftpdlib:</p>
