[Persistentperl-users] PersistentPerl release 2.21

[Sam H. <sa...@da...>]

PersistentPerl release 2.21 is available at:

    http://daemoninc.com/PersistentPerl/download.html

The changes since 2.20 are:

	- Fix too many backends problem reported by Theo Petersen.  The
	  problem is due to temp-file corruption that occurs when the
	  web-server sends a TERM signal to the frontend while it is working
	  on the temp file.  It also results in some backends failing due
	  to the corruption.  Added a fix so that signals are always blocked
	  while working on the temp file.

	- Shutdown handler should be called after script is touched.

	- Fixes for Mac OS X 10.1.  Workaround the sigpending() bug,
	  and add msync() which appears to fix a shared-memory flushing
	  problem when temp-file is expanded.
