I've written a code like below that.

Process #1 {
....
....
display.asynExec(Process #2)
....
}


I thinked that the order will be worked in parallel like this..

process #1 -> execution process #2

-> process #1 (at the same time)
-> process #2 (at the same time)

but the actual order is like this..

process #1 -> when the process #1 is ended -> process #2


"worked in parallel" doesn't mean that processes don't work simultaneously??
I don't know... ㅜㅜ

plz..... and thanks..

If process #1 is not currently running in the UI thread, then there is
the possibility they will run at the same time. If process 1 is in the
UI thread, then no, it will finish first before process 2 is allowed to run.

p.s. whether or not you see a thread switch is strongly tied to the
behavior of your OS which controls such things.
