Re: Help with Timers on Solaris

[David Sugar]

The behavior of signals in threaded applications is different between 
Linux and Solaris.  The onTimer handler and other signal related handlers 
are non-portable and are meant only to be used on platforms that have 
useful properties.  You might want to use a conditional object or 
something similar to sleep for a specified period of time or until woken, 
or to create a seperate timer management thread.
