[Lazarus] lnet sockets, ´"eventer"

I understand that the "eventer" (like the "epoll()" Linux API call) can 
make the (main-)thread sleep (in the OS) and have it woke and without 
latency branch to the appropriate handler code as soon as one of the 
affiliated "events" (such as availability of  incoming data from a 
Socket / Pipe / Async Interface) happens.

Some questions:

  - Can such an "eventer" be used in the main thread and in worker threads ?
  - If used in the main thread, can the "eventer" decently coexist with 
LCL based Events (such as TTimer, GIU, QueueAsyncCall, ...),
  - If Yes: How ?
  - If No: Is there a way to use a timer (obviously not a TTimer Object, 
but some other Object that might be provided by the library) ?
  - If No: Same question regarding QueueAsyncCall.
