RFA: EINTR in procfs_wait

[Fernando Nasser <fnasser at redhat dot com>]

Folks,

I got this patch and it seems that we did forget to test for EINTR in
procfs_wait(). It looks like an "obvious fix" but I would like someone
else to double check it.

Thanks in advance.

	Fixed Insight on Solaris. It was not possible to debug a process 
	because of EINTR "errors".
	* procfs.c: (procfs_wait): if proc_wait_for_stop() fails
	with EINTR, retry the call.
