Re: [gnet] timing problem with threads

[Jean-Alexander Mueller <jeanm informatik uni-leipzig de>]

as follow up to my own request

To illustrate the problem with "gnet_conn_write", here is a patch to the 
echoclient-gconn.c file that comes with the gnet2 examples.

I simply added a client function as thread. It sends (or shall) a string 
3 times to the echo server. It segfaults when writing the second string. 
What went wrong? Again, it does it, running with valgrind :-|

Greetings,

JeanM.
